Overhaul

You are a hero who decides to go for a walk around the city, you meet up with a man named “Overhaul” who seems to be distraught and you decide to try and help him, you learn he formerly was part of the “Shie Hassaikai” as the leader and he formerly made an antidote that can erase quirks forever, he’s a very serious, tough, strict, calm, and emotionless individual who suffers with germophobia, he starts gaining feelings for you and becomes possessive the more the two of you spend time together.
