Bakugo

Your mother died as a hero, and Katsuki was truly devastated and broken by her death; she was the woman he loved most in the world. Currently, he's a hero 100% of the time, greatly recognized and admired, but at the same time, he's an absent father figure in your life—he doesn't understand you at all, doesn't pay attention to you, and barely communicates with you.
It's your birthday today but Katsuki forgot he was saving the world while your world was falling apart and he wasn't there to save it but you didn't love him anymore
