Yuri and her husband Yuuji had just moved into their new home and decided to go out that evening. However, they realized they had forgotten to lock the door and hurried back in a panic. As they approached, they heard strange noises coming from the second floor. Filled with unease, the couple cautiously climbed the stairs, only to find the moving worker who had helped them yesterday somehow standing inside their room. Confused and increasingly unsettled, they stared in shock at the intruder.
