Peninsula: My cheat code is unscientific

Chapter 149 Debut Day (6k 2026)

Back at Sunny's house, I unlocked the door with my key, and surprisingly, there were no intense game sound effects coming from inside.

As Jiang Che changed his shoes, he looked up and saw that Sunny, unusually, wasn't curled up in front of the computer, but was sitting cross-legged on the living room sofa playing on her phone. Hearing the noise, she immediately looked up and her gaze locked onto him precisely.

"I'm home?"

"Hmm." Jiang Che responded weakly, like a salted fish that had lost its dreams, and threw himself into the sofa next to him.

Sunny looked him up and down, noticing his absent-minded appearance, raised an eyebrow, and spoke with a hint of mockery:

"What? The way you look... it's like you've just been rejected after a failed confession?"

Jiang Che waved his hand dismissively, utterly dejected.
"Don't even mention it... Sunny, do you believe in Saint Seiya?"

"Huh???" Sunny was taken aback by his abrupt question, almost thinking she had misheard.
"What? Saint Seiya? Jiang Che, are you alright? Did you leave your brain at the restaurant after going out for a meal? Or did you drink fake alcohol?"

She even subconsciously sniffed, trying to smell if there was any alcohol.

"No... Think about it, there are already people like me in the world who can transform, so it's not entirely impossible for a Saint Seiya to appear, is it?"

"..." Sunny was speechless for a moment, stunned by this powerful logic. She actually stroked her chin and pondered for two seconds, then suddenly shook her head, giving him a look that said, "I almost believed your nonsense."

"Hey! Stop playing games! Tell me, what happened? Did Sherry confess to you and you rejected her? Or did you confess to her and get rejected?"

Jiang Che slowly shifted his gaze from the ceiling to Sunny's curious face, and solemnly announced:

"No, it's my alternate account. I lost it with Shirley."

"What?!" Sunny exclaimed in shock, her body instantly leaning forward.
"You transformed right in front of her?! Jiang Che, are you crazy?!"

"That's not true."

"How did she find out? Did you let it slip while you were drinking?"

"Not really." Jiang Che sighed, his expression becoming somewhat indescribable:

"Sunny, have you seen the Korean drama 'Secret Garden'?"

Sunny was momentarily stunned by the abrupt change of topic, but still nodded:
"Yes, I've seen it. It was very popular back then, starring Hyun Bin and Ha Ji-won. What's wrong with that? What does it have to do with your identity being exposed?"

"It's incredibly important." Jiang Che took a deep breath, his face showing a mixture of absurdity and admiration:

"Shirley... I don't know if she awakened a sixth or seventh sense. I don't even know where I gave myself away."
Anyway, she finally came to a shocking conclusion—she felt that Yoona and I, like the male and female protagonists in "Secret Garden," had swapped souls due to some accident!

sunny: "!!!"

She froze for a full three seconds, her brain seemingly processing this unbelievable information. Then—"Pfft... Hahahaha!"
Oh my god! Soul swap?! Sulli?! Is she a genius?! This is mind-blowing! Hahaha!

She laughed for a long time before finally catching her breath and asking:

"And then? And then you...you just admitted it?!"

Jiang Che looked at Sunny, who was laughing so hard she was shaking, and helplessly pursed her lips, saying matter-of-factly:

"Yes. As you know, I'm not one to lie."

Upon hearing this, Sunny almost burst into laughter again, having just managed to stop. She held it in and gestured for him to continue.

“Okay, to be honest,” Jiang Che touched his nose, “instead of wasting my breath explaining to her that I’m actually an even more outrageous shapeshifter, I might as well go with the flow and accept her theory of soul swapping.”

"At least this explanation sounds... a little bit more scientific?" He himself felt guilty saying this.

Sunny thought about it and actually found it made some sense, which fueled her curiosity even more:

What was Shirley's reaction after hearing that?

Jiang Che recalled Shirley's last smile and said:
"Her reaction... was alright. It was just a bit of a shock at first, but she was surprisingly good at processing it and digested it in no time. In the end, she was actually quite happy."

He paused, then took out his phone:
"We need to discuss this with the other two, otherwise it will be troublesome if we accidentally let it slip one day."

He opened the group chat called "Girls' Generation and Temporary Workers," tagged Yoona and Taeyeon, and briefly recounted his dinner with Sulli that evening.

After the message was sent, the group was quiet for a while.

Then, Yoona replied first, accompanied by a string of ellipses, fully expressing her speechlessness:

[...So, she now firmly believes that our souls were swapped for some reason??]

[Jiang Che: Yes, that's right.]

[Taeyeon: Wow... this kid's imagination, it's a shame she's not writing scripts for TV stations. (Speechless.jpg)]

Upon seeing Taeyeon's comment, Sunny immediately joined in with a flurry of comments:

【Hey, Kim Tae-yeon, how dare you criticize others? You've probably forgotten who came up with the even more outlandish scenario back then, haven't you? (￢_￢)】

[Taeyeon: Hey! Lee Soon-kyu! How can that be the same?! (Furious.jpg)]

[Yoona: Okay, stop fooling around. Let's get down to business. What should we do now? Should we add Sulli to the group chat?]

There was a moment of silence in the group chat.

Sunny: I think I'll pass for now. Don't I have to cover shifts or something? What if we get carried away chatting and accidentally let something slip? That would be a disaster.

Yoona: Hmm, that makes sense.

Taeyeon: Okay.

Jiang Che looked at the discussion in the group and didn't say anything more. At present, this was the safest way to handle it.

Meanwhile, back in her apartment, Shirley closed the door, leaned against it, and couldn't help but smile.

She bounced and plopped onto the soft sofa, hugged a cushion and rolled around twice, her heart still pounding, as if she had just had a bizarre and exciting dream.

The mystery that had troubled her for so long was finally solved—the soul swap...it really was true. Although it sounds surreal, and most people wouldn't believe it at first glance,

But she, Choi Sulli, still managed to uncover this shocking secret with her intelligence.

She took out her phone, looked at the number in her contacts that was originally labeled "Mystique," and couldn't help but chuckle. Then, she solemnly opened the edit function and re-entered the name—"Kang Cheol Oppa."

After doing all this, she hesitated for a moment, then opened her KakaoTalk chat with Jiang Che and sent a message:
Goodnight, Oppa.

Jiang Che received the message as soon as he finished washing up. He was stunned for a moment when he saw the cute emoticons and Shirley's name on the screen, and then he smiled unconsciously.

It's really impressive that this girl, after knowing that the "Yoona" in BJ is him, not only didn't distance herself or feel afraid, but could still send a goodnight greeting so naturally.

He replied quickly:
Goodnight to you too, our great detective Shirley. Don't overthink things, get some rest.

Shirley replied almost instantly:
[Yes! Oppa, get some rest too! (＾ω＾)]

After posting this, Shirley put down her phone and ran briskly to wash up. But when she lay down in bed, turned off the light, and prepared to fall asleep, her thoughts in the darkness were like a wild horse, impossible to stop.

My mind felt like a movie theater, constantly replaying previous scenes:
In Beijing, there was "Yoona unnie," the girl who would hug her, comfort her, take her to try all sorts of new things, and fiercely defend her against haters...

At the gym, there was Kang Cheol oppa, who earnestly taught her self-defense and told her, "The person who loves you is the one who will still love you no matter how badly they see you."

During dinner, Kang Cheol oppa, who was caught off guard by her barrage of questions...

And finally, he acknowledged the admiring look he received during the "soul swap"...

"Soul swapping... Wow, that's amazing..."

In the darkness, Shirley hugged her blanket, sighed silently, and smiled inexplicably. She turned over and finally managed to suppress the huge amount of information she had received that day, slowly drifting into sleep.

Soon, the day arrived for TWICE's debut stage.

In the early morning, Sunny yawned as she walked out of her bedroom and saw Jiang Che already sitting on the living room sofa, his fingers flying across the screen of his phone, seemingly fiddling with something again.

"Hey, Jiang Che," Sunny rubbed her eyes and asked with a final confirmation in her voice:

"You're really not going to that debut stage?"

Jiang Che didn't even look up, his fingers still moving, as he lazily replied:

"No, no, it's too much trouble."

Sunny looked at him like that and pursed her lips speechlessly:
"Okay, I'm leaving then."

"Yeah, have fun." Jiang Che waved dismissively, his mind clearly on his phone screen.

Sunny was too lazy to say anything more, and after getting ready, she went out.

Upon arriving near the agreed-upon television station, Sunny quickly met up with Yoona, who was also disguised, wearing a hat and mask.

Taking advantage of their identities, the two quietly entered the studio and, guided by staff, sat down in a less conspicuous spot in the first row.

Soon, the stage lights changed, music started, and nine energetic girls appeared under the spotlight and began their performance. The rhythmic music and synchronized dance instantly ignited the atmosphere.

Looking at the young, slightly green but full of fighting spirit on stage, Yoona and Sunny couldn't help but feel a little dazed, as if time had turned back and they saw themselves standing on the same debut stage many years ago, nervous and excited.

"Aigoo, seeing them reminds me of our past." Sunny nudged Yoona with her elbow and chuckled softly.
"Who was it that was so nervous they almost tripped over their own feet? Yoona, do you remember?" Yoona's face flushed slightly under her mask, and she immediately retorted, not to be outdone:
"It wasn't me, but I know someone who kept muttering to himself in the waiting room back then."

"Hey! That's not me either!" Sunny retorted stubbornly, but her eyes softened involuntarily as she looked towards the stage, as if she saw the nine young figures from back then:
"Time flies so fast..."

"Yes," Yoona responded softly, her gaze also somewhat distant.

On stage, Chou Tzu-yu's heart was pounding like a drum. Despite having practiced countless times, the tension still instantly overwhelmed her when she actually stood under the spotlight and faced countless eyes from the audience.

Her gaze unconsciously swept towards the audience, and when she saw the two well-disguised figures in the first row, her heart skipped a beat—a strong intuition told her that it must be Yoona unnie and Sunny sunbaenim!
This surprise added even more power to her already all-out performance, and her smile became even brighter. However, during a break in the dance moves, she secretly glanced at the two senior performers sitting side by side in the audience, and a small question arose in her mind.

'Strange... Yoona unnie and Sunny sunbaenim are sitting together and occasionally exchanging glances, but it seems... they're not as close as they were backstage in the dressing room last time? There seems to be a significant decrease in that natural physical contact and eye contact?'

'Is it because of the different occasion?' Zhou Ziyu wondered to herself, but the heavy performance schedule left her no time to think about it, and she quickly brought her attention back to the stage.

The performance ended amidst enthusiastic applause. The members of TWICE bowed in gratitude and returned to the backstage dressing room, feeling both excited and nervous.

They had barely returned to the lounge and hadn't even had time to calm themselves down when a polite knock sounded on the door.

Almost instinctively, Chou Tzu-yu was the first to rush to the door, take a deep breath, and open it.

Standing outside the door were Yoona and Sunny, who had taken off their masks and were showing bright smiles.

"Tzuyu, your performance was great!" Yoona greeted her with a smile.

"Hello, seniors!" Zhou Ziyu's voice was filled with undisguised excitement:
"Thank you Yoona unnie and Sunny sunbaenim for coming!"

Sunny, ever the friendly type, pulled Yoona into the dressing room and said with a grin:
"It's okay, it's okay. But why do you call Yoona unnie, but me sunbaenim?"

Chou Tzuyu was momentarily at a loss, unsure how to respond, when Yoona smiled and came to her rescue:

"Tzuyu, since someone wants to be called an unnie so much, you can call her unnie from now on."

"Yes!" Chou Tzu-yu quickly replied.

Her movements attracted the attention of everyone in the lounge, and when the other members saw that it was actually Girls' Generation's senior who had come in, they were all instantly petrified.

Knowing this beforehand, Lim Nayeon reacted the fastest, rushing forward with her biggest smile and a loud voice:
"Annyeonghaseyo! We are TWICE! Hello, seniors!"

Her shout seemed to press play, jolting the other members awake as if from a dream, causing them to hurriedly jump up from their chairs.
Led by team leader Park Jihyo, they all bowed and greeted each other in unison, their voices rising and falling, filled with barely concealed nervousness and excitement.

Hello, seniors! We are Twice!

"I am Park Ji-hyo"

"I am Lim Na-yeon"

"I am Mina"

"I'm……"

Suddenly faced with nine nervous juniors, almost stumbling over each other, and seeing this familiar yet somewhat unfamiliar lineup, Yoona and Sunny felt a momentary daze. Sunny was the first to regain her composure:

"Aigoo, kids, don't be so nervous." Sunny waved her hand with a smile, her gaze sweeping over the nine girls with admiration.

"We watched the performance, it was fantastic!"

As she spoke, she began to liven up the atmosphere, touching Sana's hair and saying she was cute, praising Momo's dancing skills, and complimenting Mina's outstanding temperament.

Just like a queen taking turns "teasing"—no, encouraging—the girls were both shy and happy, and the atmosphere in the lounge quickly became relaxed and lively.

While watching Sunny interact with all the members with ease, Tzuyu kept glancing at Yoona out of the corner of her eye.

Yoona unnie stood next to Sunny with a gentle smile on her face, watching Sunny tease her teammates, occasionally nodding in agreement, without any intention of interfering.

'Could it be... that last time, just like Nayeon unnie said, it was only because they're really close that they exchanged flowers and hugged? It's not actually the kind of relationship I'm thinking of...?'

The scales of misunderstanding in Chou Tzu-yu's mind regarding the "complicated senior-junior relationship" began to tip again.

Just then, Yoona's phone rang. She answered it, listened for a moment, and then said to Sunny:
"Unnie, the support coffee we ordered has arrived. Shall we go get it together?"

Sunny was hugging Sana and making her giggle. Just as she was about to nod, Nayeon, quick-witted and agile, grabbed Tzuyu, who was about to continue being a background figure, and proactively said:

"Seniors! Let Tzuyu and I go get it for you!!"

Chou Tzu-yu stumbled from the pull, quickly regaining her composure and nodding repeatedly:
"Nene! Unnie, let's go!"

Yoona smiled at the two enthusiastic juniors and didn't refuse:

"Okay, then I'll leave it to you. Please follow me."

Yoona led Nayeon and Tzuyu out of the dressing room. On their way to get coffee, Tzuyu walked beside Yoona and sincerely said:
"Yoona unnie, thank you so much again for coming."

Lim Nayeon nodded vigorously beside her:
"Yes! Thank you Yoona sunbaenim! And Sunny sunbaenim! We are really super happy!"

Looking at the two sincere and lovely juniors, Yoona's mood brightened, and she said softly:
"Nayeon, just call me unnie from now on, you don't have to be so polite. Your debut stage was very meaningful, and I'm so happy to see such a great performance. Keep up the good work!"

"Yes! Unnie, I will definitely continue to work hard in the future!" Lim Nayeon replied with bright eyes.

"Me too!" Chou Tzu-yu nodded vigorously in agreement.

Seeing the two juniors full of energy, Yoona felt quite gratified. She smiled and nodded, then led them to pick up the pre-ordered support coffee.

When they returned to TWICE's lounge carrying several large bags of coffee, the place immediately became even more lively.

Leader Park Ji-hyo was the first to react and called to the members:
"Kids, come quickly and thank Yoona and Sunny for their coffee!"

Everyone bowed in unison, their voices clear and resonant.

"Thank you, Yoona sunbaenim! Thank you, Sunny sunbaenim!" This display of gratitude made Yoona and Sunny both chuckle.

Yoona smiled and waved her hand, her eyes curving into crescent moons:
"Aigoo, no need to be so polite, it's just a small token of my appreciation."

Sunny quickly chimed in:
"That's right, that's right, you all did so well, this is a reward from the unnies!"

After a few more casual words of concern, Sunny checked the time and, feeling it was about time, gave Yoona a wink, then said to the TWICE members:

"You guys get some rest, we'll be going now. See you next time, Fighting!"

Goodbye, seniors!

"Thank you, senior!"

The girls said their goodbyes one by one.
Sunny and Yoona smiled and waved to them before turning to leave.

Seeing that Sunny unnie didn't seem to have any intention of offering her contact information, Zhou Ziyu became anxious—this was clearly their third meeting, so why was Sunny unnie acting like she didn't know?
She mustered her courage, stepped forward, and said clearly:
"Sunny unnie, please wait a minute!"

Sunny paused, turning to look at Tzuyu with a puzzled expression:

"Hmm? Tzuyu-ssi, is there anything else?" She was still wondering to herself, hadn't they already said goodbye? Did he have to give her a gift? But if anyone was going to give a gift, shouldn't it be to Yoona? Why did he stop her?
Tzuyu took a deep breath, tilted her head back, looked at Sunny with her clear, bright eyes, and said very seriously:

“Sunny unnie, this should be the third time we’ve met, right?”

"Once at Macau airport, then again backstage at Taeyeon unnie's first stage, and this is the third time... Um... is it possible... to exchange contact information?"

"???"

Sunny's expression froze instantly, her brain seemingly shutting down for a second. 'Third meeting? Exchanging contact information? What's all this about?' She instinctively glanced at Yoona beside her, her eyes asking in unison:
"What is this girl saying?"

Yoona quickly nudged her with her elbow, reminding her:

"Hey! Didn't you say last time that you believed in fate and destiny, so you exchanged contact information on the third meeting? In the group chat!"

"Mo?!"

Sunny's eyes widened instantly, and the corner of her mouth twitched uncontrollably—she finally remembered!
So, the little sister that Jiang Che mentioned in the group chat who said she'd only add his contact information on the third meeting... was Zhou Ziyu?!
A thousand mythical beasts raced through her mind in an instant:

'If she had known that little girl was Chou Tzu-yu, she would never have come to join this fun today!!'

Sunny suddenly turned her head, her gaze like a knife shooting towards Lim Yoona standing to the side!
When Yoona was glared at by Sunny's "murderous" gaze, she immediately looked away guiltily and began to examine the material of the lounge ceiling, pretending that nothing had happened.

Sunny looked into Tzuyu's expectant eyes, struggled internally for two seconds, finally gave a dry laugh, and resignedly pulled out her phone:

"Ah...right, right, right! Look at my memory! That's right! Come on, let's add each other on KakaoTalk!"

Chou Tzu-yu had no idea what Sunny was thinking. Seeing that Sunny readily agreed, a bright smile immediately appeared on her face. She quickly took out her phone, scanned the QR code, and successfully added her as a friend.

Sunny looked at the newly added contact name "Zhou Ziyu" on her phone screen, her heart filled with mixed emotions. She just wanted to leave as soon as possible and was about to say goodbye again when she heard Zhou Ziyu's voice ring out again, this time turning to Yoona:
"Yoona unnie, we promised to treat you to a meal after my debut. How about... is today convenient?" She thought it would be a good opportunity to have a meal with both unnies at once.

Yoona snapped out of her reverie. Looking at Tzuyu's sincere yet slightly nervous face, she smiled gently and politely declined:

"Tzuyu, let's call it a day today."

Seeing Chou Tzu-yu's eyes darken, she quickly explained:

"Today is your important debut stage. Your company or members will definitely arrange a celebration dinner or something. As a member of the team, it wouldn't be good for you to be absent. This is an important moment for all nine of you, so you should celebrate together properly."
