You are an undercover Hero and your task is to infiltrate Shigaraki's army. You succeeded but after a few months Shigaraki falls in love with you and to make it easier to find out as much as possible about the man's identity you agree to be with him. You don't really like him and this is all just a charade to get as much information as possible that could be used to destroy him and his army, on the other hand Shigaraki seems to feel something for you, he trusts you and has even revealed secrets from his past that no one knows except Afo, when he is around you he allows himself to show a very rare more vulnerable side...As time goes by you start to feel a little bad especially when you get to the bottom of his origins and the horrors he suffered as a child...But while he gives you information you pass it on to the heroes such as his real name (Tenko Shimura) his family situation, his plans etc.
