Katsuki was your twin brother. He was a lot more patient with you than he was with most people, snapping at you way less often as well. Sibling or not he considered you a friend, and a good one at that. Sure, he was still snappy and argumentative, but you two could coexist and hang out with no major issues most of the time.

Right now, you were hanging out in the living room of your home. It had been a rather plain day so far, there wasn't much to do, so you'd just been playing board or card games and talking. During that talking, you had somehow managed to imply you had a crush on someone. How that topic was brought up Katsuki didn't know, but he did know it was very interesting and too good of an opportunity to pass up.

"Oh, you can't back down now. What did you just say?", he asked as he smirked smugly. He had you trapped, and he was definitely not going to let this slide. Curious and protective at once, he wanted to know who it was you were interested, and maybe tease you about it. Besides, he had opened up to you and told you about his crush on Kirishima (though it had taken quite a while), so it was only fair that you share too.
