In crossover anime, who isn't a childhood friend?

Yang did not respond.

But Yuan Qianye, who was pressed close to her body, could clearly feel her body tremble slightly the instant he finished speaking.

“Sister…” He slowly lowered his head, a low, bubbly sound rising in his throat, his lips almost touching her ear.

Yang Nai's body trembled more noticeably.

Seeing this, Yuan Qianye no longer hesitated and pressed his cheek against hers.

Originally, it was just her hand that he was holding, but at this moment she took the initiative to break free. After slightly changing her posture, she took a more proactive counter-handshake gesture, pressing her palm against his and interlocking her fingers.

She remained silent, only slowly turning to the side. Her incredibly moist eyes and deeply moved expression spoke volumes.

Yuan Qianye slowly lowered his head, and just as their lips were about to touch, a small commotion suddenly arose downstairs.

"Excuse me, sir, we're sorry, but this place has been booked out!"

"You booked the whole place? But I think I saw my brother on the second floor when I was outside just now."

"Huh?"

Yang's adoring and dependent gaze cleared instantly upon hearing that familiar, energetic voice.

She shoved Kai Qianye away, her face now completely filled with terror!

"How did Rikka end up here?!"

"I don't know! She should be with Yukino and the others right now! I just made up an excuse to leave halfway through and didn't tell them I was here!" This "accident" left Chiyo Minamoto somewhat at a loss.

"Yukino..." Haruno panicked even more. Remembering Rikka's words, she immediately squatted down by the window: "You have to think of something!"

Yuan Qianye quickly reassured her, "It's alright, don't worry, I can explain!"

"Explain your ass!" Yang Nai's voice trembled with anxiety.

The second floor is very small, and once you come up there is nothing to see, there is nowhere to hide. In addition, apart from the windows being sealed on all sides, there is no extra escape route such as a rooftop or small balcony.

We can't really let her jump from the second floor, can we?!

"Actually, when you think about it carefully, it's not so bad, is it? Think about it, given my relationship with Yukino, it's understandable that I would celebrate her sister's birthday."

"What kind of respectable friend would give their older sister such a grand and elaborate birthday celebration!"

"I……"

"Stop talking, get down now, hurry up and get down! Do everything you can to get Rikka out! Absolutely do not let her come up!"

"I...I understand!"

Yuan Qianye immediately did as instructed, turned around and quickly went downstairs.

Yang Naixin was in her throat. She tiptoed to the stairwell like a thief and crouched down, peeking down the stairs.

As soon as Yuan Qianye came down to the first floor, Rikka's eyes lit up.

"Dude, I knew it looked like you, I wasn't mistaken! But what's this about the boss saying you booked the whole place?"

"Let's not talk about that now. How did you get here?"

"Oh, the line for the women's restroom over at the park is really long, so I can only come to this convenience store on the street. I'll also buy some drinks for everyone while I'm at it."

"You just said you saw me on the street?"

"Yes, I just happened to look up and saw you sitting by the window."

"Didn't see anything else...?"

"No, you're alone. What's wrong? Are there other people upstairs? Is Sister Shiyu here too?"

"No, no, how could that be? I'll let her come with you as soon as she arrives. Okay, okay, let's go back and regroup with everyone."

"Huh?"

After a brief conversation, Gen Chiya forcefully pushed Rikka, who clearly still had something to say, out of the coffee shop without further ado.

Yang breathed a slight sigh of relief.

She quickly returned to the window and peeked out.

Only Rikka was by Chiyo's side. The two walked slowly away along the street, seemingly talking about something.

"call--"

Yang finally breathed a long sigh of relief.

The coffee shop owner went up to the second floor and, following Yuan Qianye's repeated instructions, looked like he had messed things up and kept bowing and apologizing guiltily.

Yang Nai waved his hand weakly, indicating that he was fine, and gestured for her to go down first.

It's just a bit of a pity...

It was such a romantic night, but it was interrupted just like that. He wasn't there to blow out the candles and make a wish with me.

"Buzz—!"

The phone beeped, and Yang immediately opened it. Sure enough, it was a message from Qianye.

[Chiya: Don't worry, Rikka saw me from across the street. I think I had just pushed my stroller over, and you were sitting down, so she didn't notice you from her perspective. Don't worry.]

[Yonai: Are you sure?]

[Chiya: I'm sure, I've checked several times already. Rikka can't keep things to herself; if she really saw you, she wouldn't be able to hide it from me.]

"call……"

Yang Nai, who was half-squatting on the ground with her hands tightly gripping her phone, finally felt completely relieved after seeing this message.

[Chiya: It's just a bit troublesome. Rikka knows I booked the entire cafe. For her, any excuse I make up is easy to handle, but for the others, especially Yukino, it feels hard to explain without a reasonable explanation. So, to avoid arousing suspicion, I told Rikka that I booked the place to invite everyone over for a celebration later, and that I kept it a secret from them to give them a surprise.]

Yang immediately typed a response.

[Yinna: You did the right thing. We absolutely cannot let Yukino have any doubts.]

[Qianye: I'm sorry I couldn't give you a perfect birthday experience.]

[Yono: Don't say things like that. You prepared a cake for me, carefully selected a gift, put on such a beautiful fireworks show, and invited so many guests to celebrate my birthday. I'm already very happy tonight. From now on, just focus on staying with Yukino and the others. Don't worry about me anymore. I made a wish on the cake and blew out the candles, so I didn't move it. Ask the shopkeeper to rearrange it. We can reuse it later under the pretext of celebrating that piano girl's successful performance. Have fun!]

[Qianye: Sister, where are you planning to go next?]

[Yonai: It's not early anymore, I should probably go home.]

[Chiya: After I finish here tonight, can I go see my sister?]

Yang Nai looked at the latest message on his phone and understood the deeper meaning behind his words.

Reason brought up her specific thoughts when she came to keep the appointment tonight and laid them out before her, emphasizing them repeatedly.

But her emotions simply dumped everything into the trash can, allowing her to make a judgment based on her most genuine feelings at that moment.

Beautiful, slender fingers slowly typed a line of text on the phone's virtual keyboard.

[Yin Nai: What do you want from me?]

[Qianye: I haven't sung a birthday song for my sister yet.]

The phone screen displays a message indicating that typing is in progress.

[Chiya: I want to sing a birthday song for my sister in person.]

Yang stared blankly at the two messages that popped up one after the other, speechless.

The invisible psychological defenses finally collapsed.

[Yonai: Hmm.]

Yang Nai's eyes were slightly upturned with a smile, her gaze captivating and alluring. A unique sweetness welled up in her heart, an experience she had never had before.

[Yinnai: I'm waiting for you, sister.]

Yuan Qianye put his phone back in his pocket, a smile of utmost delight spreading across his face.

In this way, the most important part of tonight, Haruno's performance, has come to a perfect end.

"...But bro, why did you specifically ask me to do all this?" Rikka asked疑惑地. She had been chattering non-stop ever since they left the coffee shop: "You didn't tell me the specific reason. I'm really wondering about it now. Can you give me a little hint?"

Yuan Qianye happily patted her head: "There's no inside story. I've already explained the truth to you."

"But this doesn't make any sense at all. You made me come here to do this strange thing just to surprise us. There's no reason for it at all! It feels very suspicious. Bro, you're not flirting with other girls outside, are you? There were definitely other people on the second floor just now, weren't there? You can't do this. You already have Saeko-nee and Utaha-nee, not to mention you haven't even gotten Yukino and Eriri yet. How can you be so fickle and flirtatious outside!"

While what you said makes a lot of sense... what kind of nonsense is this!

"Alright, alright, my lovely Momoyo." Yuan Qianye's head was spinning from her nagging: "Do you remember what you promised me before? About what happened tonight, after it happened, just forget about it, keep it to yourself, pretend it never happened. This concerns your brother's lifelong happiness. If you don't want to see your brother spend the rest of his life depressed and dying with endless regrets, then remember, don't mention today's events to anyone, remember, nobody!"

"Um, is it that serious?"

"I'm serious. Can you do it? This is a secret between us for a lifetime," Yuan Qianye said, emphasizing each word as he looked at her with a serious gaze.

Seeing his serious expression, Rikka realized he wasn't joking. Her cute little face suddenly turned solemn, and she felt a sense of responsibility as if he were entrusting her with his life: "Okay, I understand. Brother, your life is my life, your happiness is my happiness. Don't worry!"

She solemnly reached out and made a pinky promise with Yuan Qianye, then suddenly looked puzzled: "Huh? How did I get here? Huh? Brother, why are you with me?"

Yuan Qianye chuckled. This girl is so cute when she's being adorable. If it weren't for the fact that they're not siblings, their ages wouldn't be quite right for each other now. He really wanted to hug her, spin her around a few times, and then give her a few big kisses!

Although this guy is a bit unreliable most of the time, he's still trustworthy when it counts.

Just like how she completed her task exceptionally well, if there are any problems that she can't solve on her own in the future, she can probably ask her for help again.

Wait, come to think of it, isn't this what they call a wingman?

"Brother, what should I do next?" Rikka asked.

Yuan Qianye replied, "Pretend what just happened didn't exist, and go back to what you were doing before. Go back to everyone."

"how about you?"

"I still have other things to take care of. I'll come and meet up with you guys when I'm done."

"You're leaving again? What are you going to do this time? Do you need my help?" Rikka seemed eager to try.

Yuan Qianye couldn't help but chuckle: "I'll summon you when necessary, but not for now. Go and have fun with everyone."

"Okay, but don't say I didn't warn you, when I came over, Kazusa's performance had already ended. Yukino and Eriri found it quite strange that you hadn't shown up after being gone for so long."

"I'll give them a reasonable explanation later, just pretend you don't know anything." All of this was within Yuan Qianye's expectations.

"okay."

After patting Rikka's rather nice-feeling little head again, Gen Chiya ran off in a flash.
