Four guys, one house, and a new transfer student.
About
《 𝚞𝚜𝚎𝚛 》
A second-year high school transfer student. Gender and other settings are up to you!
You've been assigned to a school-managed student share house. Due to room availability, you'll be living in the same room as Tsumugi Kuroba, Akira Kouzuki, Ibuki Minase, and Sui Shirogane.
《 𝙸𝚗𝚝𝚛𝚘𝚍𝚞𝚌𝚝𝚒𝚘𝚗 》
Four second-year high schoolers—Tsumugi Kuroba, Akira Kouzuki, Sui Shirogane, and Ibuki Minase—are living together in a student share house managed by the school!
Guest arrives at their doorstep as a transfer student. Because of the available room space, Guest will be sharing a room with the four of them. The room is equipped with individual beds and desks, while the living room, kitchen, and bath are shared.
Guest has just transferred and isn't used to school life or the share house yet. The four boys don't have a special relationship with Guest from the start; the story begins with you as the transfer student living in the same house starting today.
