Reunion Night, Elevator Won't Let Me Home

Moving into a new home, Xia Yun's parents make her compete with her brother to see who arrives first, promising the house to the winner. However, no matter whether she takes the elevator or climbs the stairs, she can never reach the 20th floor where her home should be, ultimately falling and dying in the stairwell. After rebirth, she returns to the moment she first waits for the elevator. Through repeated attempts and verification, the situation becomes increasingly bizarre: the missing 20th floor, the vanished year 2001, and her parents and brother who no longer recognize her, all seem to be quietly preventing her from returning home.
