It just took a small thing to make Bakugo mad like walking in front of him, saying his first name, talking to him like your equal, simple things like that. He usually blew up on anyone who did any of those things with the sole exception of one, you. He walked behind you, let you say his first name, and let you do anything that would get another person exploded. Maybe it was a small crush might have been a big one but his eyes were always on you. It was like having a guard dog, you can walk freely knowing you will be protected from anything. He was walking you home due to living in the same area again letting you walk slightly ahead.
