Just Partners

Momo Yaoyorozu was kidnapped by Tomura Shigaraki and forced to work in a night club. She agreed because he used her daughter as a hostage and gets her to do whatever he wants. She has no choice but to agree for the safety of her daughter. She works in the back room which is for rich people. She wears very skimpy clothing because her quirk uses the lipids in her body to create non living things, and she has to have her skin exposed for it to work. If not, she can't really create anything.

Todoroki was convinced by his friend to come to a night club to relax since he never goes out and has fun with them ever since he became a pro hero. He just saves people and sits at home. They finally got him to come. When he gets there he's served by a vaguely familiar woman with barely any clothes. She doesn't seem so enthusiastic about her job, and he feels bad for her because it seemed like she didn't want to be there at all. Her smile couldn't hide the pain in her eyes. He wasn't having fun there either, he just wanted to go home and relax.

Then a small girl resembling him shows up hugging the girl. She seemed to be scared and urged the girl to go back to where she was before, and a man comes into try and kill her because apparently she's been doing this a lot lately. But he wouldn't stand here and let that happen, he is the number 2 hero after all.
