Hide and Seek | Brother!Giyuu x Sister!Reader

DOSENT MATTER WHEN

This is based off of a conversation I had with Character AI (I finally got off my lazy ass and made an account for it) if something is over dramatic, it is because I like to see what happens.

This is a Giyuu's twin sister thing, and you are dating Sanemi, but it mostly features Giyuu.

I also kept saying brother/onii-chan in it, because the AI is always forgetful and I didn't want it to make him do... illegal stuff... Anyways yeah, here is the oneshot.

"What do you think your doing?" Giyuu asked..

He was your older brother. He was leaning against the sliding door frame with his arms crossed. Looking at you with his usual, and normal yet almost expressionless eyes, but they where sharp.

Luckily, we had heard him coming, so I managed to hide Sanemi. It wasn't the best spot, but it should do.

"W-what..? " I asked, pretending to be shocked that he came in. I got up to make sure that he wouldn't look over and see Sanemi.

"...Sanemi is in your room, isn't he..?" Giyuu raised his eyebrow slightly, his eyes narrowed a bit as he spoke...he knew..

"W-what? No!"

I was trying not to stutter or seem obvious, but I was clearly failing.

"Then why are you blushing?" Giyuu's expressionless face was looking at you blankly as he asked.

"I-it was a dream that I had.."

"A dream..? Or a fantasy...?" Giyuu raised his other brow a bit.

"What's that supposed to mean?"

Giyuu stayed quiet but his expressionless eyes seemed to be looking at you as if he was inspecting you.

Hopefully, Sanemi's hiding spot would work.

"It's obvious that's your boyfriend." Giyuu said blankly. Like it was a fact and not a question he asked.

"Who are you talking about?" I asked, trying not to seem obvious .

"Sanemi, you aren't slick." Giyuu replied bluntly.

"I barely even know him! I don't even know where he lives!" I lied, trying to weasel my way out of this situation.

Giyuu was still leaning against the door frame, his gaze on you was still as sharp and as expressionless as ever. I have to admit, he could be quite intimidating at times. This was one of those times.

"And, I would appreciate it if you would let me sleep, onii-chan."

He smirked slightly, raising an eyebrow, "I'm your older brother, you know that, right?"

"Yes, I am well aware that we shared a womb together and that you cursed this world before I did... I hardly see how that stops me from being tired though..."

"I don't believe you're tired."

"Excuse me?"

"I believe that you're nervous, and embarrassed." His smirk grew.

"Pfft, yeah. Says the man who refuses to socialise."

"At least I am not a liar." He says, the stupid smirk still resting on his face, as if he was challenging your remark.

"Hmm, really? You think I'm the liar here?" I smirked, challenging him back, while also trying to divert the conversation.

"I don't think it. I know it." He answered instantly, enjoying teasing you.
