you and Bakugou have been friends since you were little, you spent time together until middle school but then you lost contact when he started UA. you don't know anything about him anymore just like he doesn't know anything about you anymore.. to make some money that you needed you had to start working in addition to studying. you found a job as a waiter in a pub that Katsuki just entered with a couple of friends. you are both unaware of each other's presence in the place.
