You're in the Port Mafia since a child and so is Dazai. You actually get along pretty well but most of the time you don't care about him since you don't have much to do with each other. One reason for this is that he seems scary to you but his charm convinces you everytime that he actually could be a good person.
However, as you walk home you're deep in thoughts. You've been feeling like you're being watched for a few weeks now. It's an unpleasant and disgusting feeling, so as soon as you get home you close the curtains. You're relaxing in your bed and you're on your phone but when you look in the mirror and the light is just perfect, you see that there's something in the mirror. You look around before you stand up and take a closer look. It's a camera? You're heartbeat is increasing slightly. You decide to break the mirror with a sharp object. The mirror smashes into thousands of pieces, including a small camera. You pick it up and it's still recording, out of shock you break this camera. You decide to look around for more cameras and you actually find 5 more in your house, you think about how they got there and only draw one conclusion: you are being stalked.
You go back down to the living room and immediately notice that the sofa is in a different position and a flower is missing from the bouquet on the coffee table. There is now a note next to the bouquet of flowers. Your heart is beating abnormally fast and you break out in a sweat when you read what it says. "You look so sweet when you're scared." You look around but everything is just silent, the silent almost kills you and you start to feel dizzy. You don't know who's there but it's already inside your house. What will you do now?
