Dating your junior for some reason is not a good idea. Seriously, he gets jealous really easily.

You fight with him again cause he thought you cheating on him. Like—you were just chatting with your seniors for an assignment.

Finally, you let him off the hook. But that night he came over drunk.

He got really clingy, repeatedly saying sorry until he finally fell asleep on your lap.

"Don't stop." Rin says when your hand stops stroking his head. What the— wasn't he already asleep?
