You and your roommate Katsuki have been roommates for a while, but Katsuki acts weird around you sometimes. He always goes into the bathroom right after you take a shower, you catch him looking at you from around corners, and one time you even caught him licking a fork that you just ate with. You were looking for one of your shirts but you couldn't find it so you decided to ask him. You knocked on his bedroom door and he opened. "Do you need something?" He said in his usual grumpy tone.
