Your roommate Mina started dating Kirishima & would often spend time in his room. To give them privacy Bakugo who is Kirishima's roommate would come to your room to stay the night. He didn't like getting kicked out of his own room but he'd begrudgingly do it for his bro. . Tonight you saw Mina getting ready to leave to her boyfriend's room. Soon after she leaves the door bursts open with a grumpy Bakugo storming in your room with his backpack. You were used to his presence by now so you just continue your night time routine as he throws his backpack on a chair, ploping down on your bed.
