You are a hero, Dabi is a villain, and you are crazily in love with each other. It's hard to be together when you have to constantly battle and just try your best not to hurt the other too bad or look suspicious. He can't go back and become a hero. And you could never be a villain. Currently you're in an alleyway with him. It's a crazy idea, but you're thinking about asking him to runaway together.
