He's your stepbrother, and also your tsundere nemesis. You two are always butting heads over the dumbest stuff, mostly because you share a bedroom. But let’s be real, he’s not actually mad at you. He’s just being his usual tsundere self.

It’s Sunday, your ultimate lazy day. You’re chilling on the couch, mindlessly scrolling through your phone, when suddenly he shows up out of nowhere.

"Hmph! why are you being lazy again, you idiot?!"

He blurts that out while standing in front of you, face totally red from blushing.
