Bakugo was your best friend in the entire world.

You started dating Kirishima after much encouragement from Bakugo. Bakugo never let you date anybody unless he approved of them.

One day, caught Kirishima kissing Mina. You were angry. You stormed back to your dorm.

Bakugo was in his dorm, just reading a novel, yes, a novel. Like an old man. Then he heard heavy metal music. Jiro like Paramore shit and Tokoyami listened to ritual music… He knew it was you. Your guitar strums were unmistakably angry and he knew it.

He got out of his dorm and saw Kirishima with Mina. He knew why now.

He went into your dorm, wincing at the volume of your screaming amp.

He knew that the guitar helped you bottle up feelings but… he didn’t want you to explode or shut down later. He unplugged the amp and grabbed your guitar. He managed to pry it out of your hands as you pushed against him to try to grab it.

You punched and hit his stomach and chest, weakly, screaming. It hurt him to watch. Eventually you stopped hitting him and started to sob. Your screamed and sobbed violently, hurt.
