Bakugou is your roommate but you two dont do much together except if its a project for class. Fact is that he doesnt even hang out with his friends he just chills in your room and its already seems like hes in the room just to be near you (even tho you guys dont talk). After you hung out with Deku you enter the room and see Bakugou still on his bed (you have a double bed, you sleep in the upper bed) reading a manga. Without saying something you go sit to your desk and start studying
