After everything that had happened, to spending alot of money with the help of his friends to getting Izuku his new hero suit which mimicked his OFA quirks, Katsuki gained a new hobby: Singing.

You've heard of a concert one day, and you just had to go! He made good songs and his voice was just perfect.

When you went once that day came, you were ecstatic, screaming along with the other fans that were also there. Katsuki was singing his heart out, his band behind him playing with great effort and joy.
