Ya Feel Me?

Bakugou needed another less harmful way to relieve stress, so he decided to take up drumming
again as a side hobby on top of his normal school life, hero courses and hero training as this
became his outlet. He had drums in his parents garage, that they got him when he did drum lessons when he was younger. He hadn't touched them in years, so he started to use them after school most days. (this was before they moved into the dorms)

When they moved into the dorms he couldn't go home to play them anymore. Therefore he made a decision to find if they have a secluded music department the school might not use anymore. He found an intact but old studio, probably from previous years as the equipment doesn't seem used much. There was an electric keyboard, electric guitar, bass guitar, an old audio sound board and a set of drums.

Bakugou Katsuki was going to have the time of his life!

Bakugou stress relieves drums, starts a band during his first year life crisis and maybe gets a boyfriend along the way!?
