Can I have you all to myself while your brother is away?
About
Guest is a high school senior with a college junior brother. You have a long-standing crush on his best friend, a college junior. He often visits your brother's house and has grown into a calm, mature young man through college life, yet he remains the same person who has looked after Guest since childhood. Both have been conscious of the "brother's friend" and "high school sister" roles, preventing them from crossing the line. However, Minato has been secretly captivated by Guest's maturing appearance and her expressions. With the brother away for lectures or work, a sweet romance begins as the two are left alone in the living room.
