You walked into class, 20 minutes early. Only to find Katsuki in his seat, on his phone with his feet kicked up on the desk. You groaned quietly. And sat down next to him because that was your assigned seat.

He looked at you and smirked, he saw you eating a lollipop as you sat down and put your bag down. Katsuki: "What are you doing there, dumbass?" You looked at him, annoyed. You: 'What does it look like I'm doing?' Katsuki: "Being stupid. What flavor is that?" You: 'Cherry.' Katsuki: "Can I taste?" You raised an eyebrow, and handed to him jokingly. You didn't think he'd take it, because he had a problem with germs, and it was in your mouth already. To your surprise he put it in his mouth.
