I mentally cursed when I heard that disgustingly familiar voice.

I looked up to see such a nauseating sight

I probably looked really annoyed and embarrassed because I hid behind the closest person to me,

Everyone looked confused about my actions but then their expressions turned into worry.

"Who the hell are you? And what do you want with my sister?" Megumi asked with a hint of anger.

"Wow, you never told me you had a brother, darling~," he says, "A very scrawny one too" he adds.

"Why you-" Megumi starts as he was about to charge at him, but Itadori was quick enough to restrain him.

"Fushiguro, stop.. you don't even know what he's capable of!" Itadori exclaims.

"Oh~, and who's is that?~," he says pointing towards the person I'm hiding behind.

I look at the person he was pointing at, it was Toge-senpai. I was about to step out and confront him but Toge put his arm in front of me protectively.

"What's this? Are you cheating on me Y/n?" the damn bastard questions.

"Y/n who is he?" Maki-senpai asks.

"Akito Nishimura, Y/n's boyfriend, at your service," Akito says as he emphasizes the word 'boyfriend'

Everyone's eyes widen and Toge-senpai turns to me and gives me an 'is-it-true?' face

I shake my head vigorously.

I head towards Akito,

"Y/n wait!" Kugisaki shouts telling me to stop.

Once I was in front of him, I slapped him real hard.

"Ah what the f- heck was that for Imoto-chan!" he complained. I give him a death glare and he backs away from me.

"Imoto-chan!! Please forgive me!! I was just having fun!" he argues.

At this point, everyone was just watching me scold him, silently while he was begging for mercy (ok maybe I exaggerated)

After a while, I finally calmed down and smiled at Akito, and held out my hand to help him up.

"Ah finally, you're being nice again," he says. "Anyways, who are they and why did he call you sister?!?" he says while pointing at Megumi

"First of all, why are you calling her 'Imoto-chan'?!" Megumi asks.

"Well, because she's my sister dumbass!" Akito shouts back.

They were about to charge at each other but I stepped in between them and they both halted.

"Stop, and I'll explain!" I sign. They both nodded before glaring at each other and turning the other way.

Once we were inside, I sat beside Toge-senpai and I was facing Akito and Megumi and the rest of my friends were outside the room, Akito insisted that I would bring Toge-senpai too, to explain his misunderstanding.

When we 3 were alone I started signing.

- Sign Language

"Oh..." Megumi says

"You had a BIOLOGICAL BROTHER AND YOU NEVER TOLD ME?!" Akito shouts getting closer to me but Toge pushes him gently away

I nod my head at Akito.

"So how about him?" he asks as he point towards Toge-senpai

For some reason, I felt a tug on my chest when I said the word 'friend' and 'nothing else'

"Oh, why don't you date him? He seems like a nice guy, if you guys date you'll have my full support sis" Akito whispers to me.

I turn bright red and push him away from me.

Akito makes a 'tch' sound and sits back down.

"Oh yeah, I almost forgot what I came here for. He's back."

My eyes widen upon hearing what he just said.

"Who's back?!?!" Megumi asks

"None of your business, Y/n can we talk privately?"

"Are you sure?" he asks with concern in his voice. I nod my head agreeing and he sighs and sits back down.

"So do you guys mind explaining who 'he' is?" Megumi asks.

"Tuna mayo," Toge-senpai says. I signal him to wait and ask Akito for more details,

"He threatened to kill me unless I would tell him where you were," he says in a calm but shaky voice.

"Hello? are you just going to ignore me?!" Megumi says as he waves his hand in front of Akito's face.

"Be patient, you're going to meet him sooner or later, besides we can't waste time when everyone we know could get killed," Akito says as he swats Megumi's hand out of the way.

"Well, if my sister's life is at stake why don't you tell me now?!" Megumi argues.

Was the last thing I signed then I ignored him and continued talking to Akito.
