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

After waiting for about ten more seconds, there was still no movement from inside the door.

"My sister must be fast asleep," Yukino guessed.

"It's also possible that she has a fever and is lying in bed, having lost the ability to perceive the outside world." Mrs. Yukinoshita became increasingly worried.

She began to silently reflect on whether it was too early for her to hand over part of the family business to her eldest daughter, causing her to have to juggle studies and company management at the same time, which put too much pressure on her.

But there's no use thinking about it now.

She took out her phone and dialed her daughter's number.

Meanwhile, in the bedroom a dozen steps away in the apartment.

"Why would anyone be looking for me now?!" Yang Nai's voice was almost distorted with terror; even the simplest sense of logic had failed her!

"This is your apartment, sister! It's no coincidence that your mother is calling now, she must be here!" Yuan Qianye had already activated her God's Eye to see the situation outside the apartment door and tried to guide the conversation.

As for why he didn't give a heads-up sooner... when someone is being intimate with their loved one, they're naturally focused on pleasing both themselves and their partner, so how could they have the energy to pay attention to anything else!

"Yes, it must be Mom... What should I do, what should I do, what should I do..." Yang Nai held the phone, her voice almost distorted with terror.

"Sister, calm down, listen to me, it's okay. Even if Auntie comes, it's alright. Do you remember the cake I brought? Let's get dressed quickly and go open the door. Just say I'm celebrating your birthday! We can fool everyone!"

"How could we possibly hide it from you! It's already suspicious this late, not to mention that we haven't opened the door since the doorbell rang, which is enough to convict us both on the spot!"

Looking at the seemingly calm Yuan Qianye, Yang Nai realized that he was only putting on a show.

The incessant ringing of the phone was like a death knell, startling the two of them into a panic.

There was no other choice at this point; there was only one way.

Yang Nai resolutely said, "You go out first."

Yuan Qianye was taken aback: "You mean, tell Auntie about our relationship?"

Yang Nai's face flushed crimson, and she emphasized, "No, it's not that. You should... step out first!"

Gen Chiya finally realized what was happening: "Whoa!"

Yang was extremely embarrassed and annoyed, not knowing whether this guy was panicked or enjoying it, as he was still full of energy.

Even if you haven't eaten pork, you've seen pigs run. According to the descriptions in so many books and works, shouldn't the situation be exactly the opposite?

Meanwhile, Chiyo found Yono, whom he usually called "older sister," to be incredibly cute. In this tense moment, she even let out a tiny, yet still noticeable, whimper.

Damn it, if it weren't for the emergency...

The two immediately got out of bed and dressed, with Yuan Qianye dashing into the bathroom.

He just finished showering and left all his clothes on the sink outside the bathroom.

When he returned to the room with great ease, Yang Nai was still so weak that she couldn't even lift her legs, so he had to rush over to help her.

"There's only one way now: you hide," Yang Nai said with his back to him.

"If we get caught like that, things will only get worse, won't they?" Yuan Qianye helped her fasten her clothes.

Sensing that Minamoto Chiya clearly had other thoughts in his mind, Yono turned around with a cold face and pressed her forehead against his: "Minamoto Chiya, I can tell you this, if our affair is really found out by Mom, then I will kill you first, and then I will commit suicide myself."

Her murderous intent made it seem like she wasn't joking.

Yuan Qianye's Adam's apple bobbed slightly, a hint of excitement in his voice.

Haruno actually has a hidden yandere attribute, just like Saeko?!

Really like!

"There's no need to make it sound so serious. I'll just go along with my sister."

The cell phone stopped ringing, but before the two of them could relax, the doorbell rang again.

At the same time, the phone rang again, a beat too late.

Despite feeling hot and dizzy, Yang Nai forced herself into a state of absolute rationality. She picked up her phone: "I can't ignore this call, otherwise Mom will definitely worry and I don't know how she'll react. Anyway, I'll try to buy you as much time as possible. During this time, you should try to erase all traces of your existence!"

Yuan Qianye didn't have time to reply to her anymore; every second was precious now. He started cleaning up the toilet paper scattered on the floor, not even leaving the trash can untouched, and tiptoed out of the room again.

At that point, they didn't care about the dirt anymore; they just tore it up and flushed it down the drain.

He suddenly had an extremely absurd sense of déjà vu.

He was engaged in illegal activities, and Haruno was his accomplice, while his parents-in-law and Yukino outside the room were disguised as law enforcers and prosecutors.

The examples may not be perfect, but the sense of oppression and tension is exactly the same!

At the same time, Yang Nai answered the phone, speaking in a groggy voice as if she had just woken up: "Hello... Ah, it's Mom..."

At the same time, she looked at Yuan Qianye, pointed to the first-aid kit in the living room, and made a drinking motion.

Yuan Qianye immediately understood and hurriedly opened the medicine box and took out antipyretics... However, it was only then that he suddenly realized what was going on.

Can someone take medicine after drinking alcohol?

Sister, you're really panicking.

He put the fever reducer back, tore open a fever-reducing patch, and held it up to Yang Nai's forehead.

"Um...it's nothing...I was sleeping...I didn't hear it. Did you ring the doorbell?"

Yang Nai arrived at the center of the living room, biting her lower lip, her gaze quickly and nervously searching for the safest hiding place for Yuan Qianye.

At this moment, Gen Chiya opened the bedroom window to its maximum and frantically fanned the air with a folder from Yono's desk, trying to dissipate the special scent of their passionate, hormonal mingling as quickly as possible.

This kind of taste might be indistinguishable to Yukino who lacks experience, but it would be highly likely to be exposed to her experienced father-in-law and mother-in-law, so they cannot let their guard down!

Of course, the best-case scenario is to not let them into the room later, although the chances of that are slim.

"Huh? Mom, you're at my door? What, Dad and Yukino are here too?"

Yang Nai's fear intensified at this moment.

After the smell in the room had almost completely dissipated thanks to Gen Chiya's miraculous efforts, he went to the dining table where the two of them had been eating. He took out an extra set of cutlery and plates and used the remaining sauce to smear them, creating the illusion that three people had been eating the leftovers at the same time.

After that, he went to the entrance and hid his shoes in the top cabinet of the shoe cabinet, a cabinet he rarely used. He also made sure to turn off his phone.

"Okay, I'll come open the door for you right away." Yang Nai hung up the phone.

"There shouldn't be any flaws anywhere. Sister, take another careful look."

"Your movements are so fluid and smooth, how come you seem so skilled at them?"

"Is this the time to talk about this, my dear sister? Where should I hide?!"

Yang Nai's apartment, where she lives alone, is not large; looking around, there are indeed few places where an adult could hide.

Balcony, cabinets, under the bed...

Yang Nai gritted her teeth: "Go stay in my closet and don't make a sound!"

Yuan Qianye noticed that Yang Nai's hands were trembling badly, and quickly grasped her hand: "Don't worry, sister, the worst that can happen is that we'll be discovered."

Yang Nai smiled sinisterly and terrifyingly: "You'd better pray that doesn't happen, or you can expect to die with me!"

Without further hesitation, Yuan Qianye nimbly slipped into the wardrobe and gently closed the door.

After watching him finish all that, Yang Nai took one last look at herself in the bathroom mirror. Thankfully... today's Chiya wasn't like last time, because he kept begging for kisses and didn't leave any marks on other obvious parts of her body. It was a stroke of luck amidst misfortune.

As for why his face was so red, it could be completely explained by the fact that he had been drinking.

It works!

She patted her cheeks hard as a form of encouragement, and then her facial expression quickly softened and became drowsy, her eyes changing from resolute to a hazy look as if she had just woken up.

She took a deep breath at the front door and unlocked it.

"Sorry, sorry, I was sleeping too soundly... But Mom, Dad, and Yukino, it's so late, you've come to celebrate my birthday!"

Yang Nai apologized as soon as she opened the door, then pretended not to understand. Finally, when she saw the cake her father was carrying, she was pleasantly surprised and suddenly realized what was going on.

The subtle, natural changes in facial expressions and tone of voice were displayed with remarkable smoothness, perfectly capturing the demeanor of a young girl who has just woken up from her sleep!

Good job! Keep it up, and you'll be fine from here on out!

Hiding quietly in the closet, Yuan Qianye secretly cheered himself up, using his omniscient perspective to silently observe the situation outside.

"We were planning to give you a birthday surprise today, but you sounded so weak on the phone and we were worried about you, so we just came over."

After Mrs. Yukinoshita entered the house, she explained that she smelled a strong odor of alcohol the moment her eldest daughter opened the door, but because she was concerned about her daughter, she didn't say anything.

Seeing the fever patch on her forehead, Mr. Yukinoshita asked worriedly, "Do you have a fever? Are you feeling unwell?"

Yang Nai nodded and said, "Uh, it's okay. Actually, I don't think I'm in any problem. I just felt dizzy and couldn't tell if it was because of the alcohol or because I had a fever. I was just taking precautions. Now that you guys have woken me up, I don't feel so dizzy anymore."

"So it's just that you're feeling a bit unwell from drinking too much? And that's why you slept so soundly, right?" Mrs. Yukinoshita hit the nail on the head.

Seeing this, Yang Nai smiled and stepped forward to hug her, begging for forgiveness: "Really, Mom, I only do this occasionally. Today is my birthday, please let me off the hook."

"You silly child." Mrs. Yukinoshita gently tapped her forehead, but at least the situation wasn't as bad as she had thought.

She had been very strict with her eldest daughter since she was very young. Now that she has grown up and can stand on her own in some ways, some of the restrictions should indeed be relaxed.

"Sister, you should say less of those things that make Mom and Dad worry. Dad didn't even have time to sit down after getting home before coming straight over to you," Yukino said helplessly.

"I know, I know everything... Ugh!" When Yang let go, her body swayed uncontrollably as she stood up again, as if she was about to fall.

The effects that Qianye exerted on her with all her might were significant and had not been eliminated at all.

In this state of weakness, it would probably take several tens of minutes to recover. The fact that she can stand up now and control the uncontrollable trembling of her body to the greatest extent is already an amazing display of willpower.

Yukino, who was closest, quickly caught her older sister and then sighed, "It's unbelievable. My sister, who used to tell me that our father, who was covered in alcohol, smelled the worst, has turned out like this."

Not only Yukino, but also her father and mother regarded her reaction as a normal drunken reaction.

Mr. Yukinoshita, caught in the crossfire, tried to salvage his image: "Dad didn't want to drink either, but he had no choice because of work and the family business..."

But neither of his daughters paid him any attention; only his wife covered her mouth and smiled faintly, giving him a comforting look.

He sighed as if he had aged several years in an instant, and carried the cake to the dining table.

Looking at the slightly messy desk that hadn't been tidied up, he didn't think there was anything wrong with it, except for one thing.

He put down the cake, slowly picked up the wine glass, and stared at the three sets of tableware on the table...

Oops!

Yuan Qianye, who had been silently observing from inside the wardrobe, suddenly felt her heart leap into her throat.

The situation was too urgent just now. He was trying to create the illusion that the three of them were eating together. He had prepared all the tableware, but because of the time constraints, he forgot to add a wine glass!
