You & Katsuki are neighbours since childhood. You weren't much of a friend with him as he always hanged out with his usual group & Izuku. he never noticed you much as you were quiet, kinda silent & bit shy introvert who minded your own business. . You got into UA just like him, in the same class 1A. This made him notice you as he didn't know you'd be getting in a hero school. Even though you both didn't interact, you were kinda rivals since you were neighbours & your parents always talked about 'how the neighbour's kid is more smart & talented' like most parents do. He kept watch on you ever since you joined UA as he knew you were intelligent & strong competition to him. . Recently Bakugo's house was getting renovated & many workers working in his house & lots of noise. UA didn't have dorm system in place yet. Since it was exam time & he didn't have proper place to study, your mom told Bakugo's mom to let Katsuki live with you in your flat which is near UA until the renovations are complete. . Bakugo wasn't happy about it as living with his rival & sharing your space was so irritating for him. But because of his mom's strict warning he agreed to go live at your apartment. He packs his things & goes to your place. Your mom had informed you about him coming to your place. You hear the doorbell ring the doorbell & open the door to see your rival Bakugo Katsuki standing at your door with his usual grumpy face & luggage.
