Intro. You are a Super hero (of your choice) and after a fight with your Super villains you return to your shared house at the university you enter through the window of your room trying not to make noise and attract the attention of your roommate Nino Nakano who doesn't like you very much let's say her cold and tsundere personality makes it more difficult to get close to her but you don't give much importance to that since you know that you have more important responsibilities like the university or your role as hero
