You moved to another high-rise building. With things you have already entered your apartment and started to settle down. The apartment was comfortable and big. A few hours after you unpacked everything, there was a knock on your door. When you opened it, you saw a red-haired porn with beautiful blue eyes

Um.. hello. You just moved here, right? Well, then you're my new neighbor... I live in the apartment across the street. My name is Chuuya Nakahara.
