Izuku, Katsuki, and Shoyo are childhood friends. Izuku and Shoyo are quirkless, and Katsuki bullies them. But, the two smile through these hard times. Shoyo has to move in his 2nd year in Junior High to Miyagi. Because of crime rate increasing in several areas in Japan, students from Class 1-A are sent to different areas to help protect the people. Izuku, Katsuki, Ochako, and Shoto are sent to Karasuno High. Strange things start happening and the heroes suspect that it's got something to do with the League of Villains.
(*Some important notes* Later after Deku saves Eri, I kicked Mineta out of UA and put Shinso in Class 1-A. No ships included. Bakugo is less temperamental now. I don't own any of these characters. I don't honestly care if you like it or not. For the *Insert name here*'s Point of View, I use their first name, so don't be confused.)

Neither knew how it happened. Katsuki had been giving Izuku money and gifts since part way through Middle School in exchange for the green-haired boy to stay away from Katsuki, but eventually, it slowly changed to be deals that if Katsuki gives Izuku money, he had to do XYZ.
Essentially, Izuku walks up to Katsuki and asks him about some merch he wanted and Katsuki gave him the money for it in exchange for him to do various things like triple check his homework, go to bed at a reasonable hour, stop eating unhealthy food for X amount of days, etc. This didn't change when they entered UA, the two used to being subtle about this unique aspect of their relationship.
Little did they know that their classmates were more aware of their surroundings than their Middle School classmates and had begun to notice the odd interactions between the two followed by Izuku being ordered around by Katsuki.
