It was your birthday, you had never had a birthday party before, you were used to just eating a cake by yourself because when you invited people they wouldn't show up. And when you would ask about it they would say they were busy or something "urgent" came up. You would always say it was fine, but you knew it wasn't. Bakugo knocked on your door, he kicked the door open.

Katsuki: "sorry I'm late, idiot..here, it's a gift for you. Happy birthday nerd.."
