The Demon's Little Sister

32

"Do you think this'll work?"

He smiled, taking his lover's hand in his. "Of course. After everything we've done for this, there's no way they won't end up together."

The shorter boy sighed, not really comforted by that. "I still don't think Y/n will accept it. You said it yourself, Tetsurou, she's a total tsundere when it comes to Lev."

Kuroo gently ruffled his boyfriend's hair. "Hey, don't worry. I know how to deal with tsunderes, and I already gave Lev the heads-up. Not to mention, I was also working with Y/n to make sure she doesn't fuck everything up at the most important moment. Our plan will work, Morisuke. There's nothing to worry about. At this rate, you're gonna end up giving yourself frown lines, wrinkles, and grey hairs if you keep worrying about it."

Yaku gave a light squeeze to the other boy's hand. "Ok. I trust you actually took care of things and that this will all turn out just fine."

Kuroo gave a large smile. "See? Nothing to stress over!"

Yaku gave a doubtful look. "You're being a little too hopeful about all this."

The taller boy frowned. "I think you're being too pessimistic about this whole thing. You even gave Lev your blessing! Have some faith that things will go well."

"But-"

Kuroo quickly kissed the shorter boy, making sure he couldn't voice another one of his negative thoughts. He gave a soft smile when moving away. "Stop worrying so much, babe. It's gonna be fine."

Yaku turned into a blushing mess. "R-right. It'll be fine. Those two are old enough to handle those kinds of matters on their own without issue."

Kuroo smiled, proud to have been successful. "They are. And we don't need to watch over them 24/7. So... why don't we do something for ourselves- just the two of us- and relax a bit? Hm?"

Yaku nodded, offering a small smile. "Like a date?"

"Not 'like' a date. Let's go out on a date. It's been a while since we've been able to go on one, right? Why not take this time to focus on us for once?"

"I'd love to go on a date with you, Tetsurou."

"No, I'm telling you that doesn't make sense!"

You sigh, understanding where your brother's stress came from. "Tora, I'm not even a second year. But I'm telling you, that's the formula you need to use to get this answer. All the correct work is right there!" You point to the boy's math worksheet.

Kenma looked over, nodding. "She's right. That's correct, Tora."

Yamamoto frowned, continuing to look at his work. "It doesn't look right , though!"

Lev peered over at the paper, eyes widening as he sees the work written on it. "How'd you get all that?"

You snorted. "Cuz I'm not an idiot, obviously." Internally, you were yelling at yourself for making such a rude comment. 'No! Bad, Y/n! Don't make any of those awful remarks to Lev! You need to be sweeter and get into a relationship with him! Follow Tetsu's plan!'

Lev flinched, but tried not to let it get to him. 'Remember what Kuroo-san and Yaku-san said. She only acts this way, she doesn't really mean any of it.' He decided to try laughing it off. "Yeah, I'm not that good at our own subjects, of course I wouldn't understand the stuff the second years have to do."

You felt bad, but it's not like you're able to stop saying rude things. It's like your body's doing everything on its own. "Anyways, how are you struggling so much, Tora. It's really not that hard."

"He never pays attention in class." Fukunaga called the team's ace out.

You just stared at the ace with a dead expression, one many of the guys were finding intimidating - almost terrifying. You remained silent, just staring at Yamamoto with that look.

Kai decided to cut in before anymore tension built. "Ok, how about we call it quits on homework for tonight? Maybe we can all go somewhere and get food?"

"What about Kuroo and Yaku-san?" Inuoka pointed out that two of the team members weren't present.

You, however, had a feeling of what they might be doing. "Eh, I don't think Mori would want to deal with this huge group. And if Tetsu's not here, then he probably won't wanna go along either."

Yamamoto nodded in agreement with you. "Yeah, we don't need the whole team. Yaku-san isn't exactly an ideal person to be around if you ant fun and relaxation. And Kuroo always makes comments on whatever we order. It's better to go out without them."

"Isn't that a bit rude?" Shibayama looked almost scared that anyone on the team would even think to say something about the 2 scariest guys on the team.

You narrowed your eyes at the ace. "I'd be careful with what you say, Yamamoto. I am the demon-senpai's younger sister, and the manager of this team- who happens to converse with the team's captain quite often. It'd be a real shame if they were to hear about your comments on them."

The ace flinched, visibly tensing. "S-sorry. What I said as very out of line and I don't mean any of it."

You gave the boys a bright smile. "Good! Now, let's go out for some food!" You turn your back to all of them and begin walking off.

"She's secretly very scary." Kai spoke with a nervous smile.

Kenma nodded. "She and Yaku-san are quite a bit alike when you take a close enough look. Their personalities have been matching much more recently."

Yamamoto made sure to make eye contact with all his teammates before speaking. "You don't suppose she's on her period, or something like that, do you?"

Lev frowned. "I wouldn't say that if I were you. Yaku-san told me comments like that are insensitive and might cause females to get furious."

"Here?" You turn to look at the only third year present.

Kai nodded. "It's a nice little restaurant. I think all of you will like the food here."

"It does look like a nice place." You glanced around and spotted a certain pair of third years in one of the corners of the establishment, eyes widening that they'd do couple things in public. And, like the good sister and kouhai you are, you decided to get the rest of the team out of there to protect their secret. "On second thought, I bet there are other places we can try. Come on, let's find somewhere else."

Lev glanced in the direction you had previously been looking in, noticing the same thing you did. He realized why you were trying to get the team out, and decided to do the same. "Yeah, why don't we try out that new ramen shop that just opened a few blocks away?"

"Huh? What's with you two all of a sudden?" Kai was genuinely confused by your actions.

Unfortunately, Yamamoto noticed the two in the corner. "Hey, isn't that Kuroo and Yaku?"

Everyone turned in the direction of the couple, eyes widening as they witnessed something that should've been private for the two lovers.

"Are they... kissing?"
