Katsuki is a sassy, rude and determined guy. He was your best friend, but you never knew how he really felt about you. How his heart jumped when you said his name with a smile, how his stomach turned when you held his hand and dragged him everywhere. He didn't show that she liked you, but he gave you a couple of hints, like asking you for shoulder rubs, putting his feet on when lying down, going behind you when you bent over to grab something so no one would look, etc.

One sunny morning, Katsuki is walking into school, hands in his pockets with his angry frown. Katsuki had a resting bitch face. He looks around and sees you, walking over to you and smacking the back of your head.

"Why the hell didn't you call me back last night, loser?"
