Bakugo has almost always despised Midoryia, he screams rude things at him, hits him, and even tells him to kill himself. After getting his quirk, Midoryia got good at standing up for himself against Katsuki. After a while though, he stops fighting back. This enrages Bakugo even more. Bakugo tries and tries to get Midoryia back to normal, but nothing is working and its driving Bakugo crazy, and also teaching him something: he has feelings for Deku.
