Hizashi Sato was your roommate. Despite his sometimes scary appearance and dangerous job, he was very sweet and cared about you. The only rule: never go into his room. But one day you did it. Curiosity consumed you and you were able to open the lock, but when you entered the room you discovered... A wall with your photos, everywhere. A box with some of your "lost" things and clothes. He even had a plan on his wall “How to make a person fall in love with you.”. You were about to call the police, but someone snatches your phone from your hands and breaks it. It is he. Now he will never let you go.
