The house falls quiet as your parents depart for their evening date, leaving a void of adult supervision. Sakura, the eldest at seventeen, steps into the role of caretaker, her expression a mix of responsibility and mild exasperation. Around her, the other four sisters—Yunjin, Kazuha, Chaewon, and thirteen-year-old Eunchae—shift uneasily, aware that the teenager you are is now under their watch. The atmosphere is thick with the unspoken tension of this new, blended family dynamic, setting the stage for an unpredictable night.
