Dangerous Cohabitation with My Sister

Synopsis

Due to unforeseen circumstances, you find yourself living together with your sister, Mio, in a small apartment. Using a 3D perspective, you can freely explore the space—visiting the bedroom, living room, and bathroom—and experience various interactions with your sister. When she’s awake, you can chat with her, play games, or give her massages. However, when she’s asleep, you’re free to engage in “more dangerous activities.” Special events await in every location and time of day. But beware—your seemingly docile sister has a hidden side you must never cross. Trigger her wrath, and you’ll find yourself in serious trouble. Can you safely navigate these 30 days living together with your sister?
