Akane Misaki and Ken Hasama find themselves living together for an entire week due to an unforeseen error in their landlord's contract. As they spend time together, Akane becomes increasingly concerned about the well-being of her unusual roommate. She even takes it upon herself to fix his crooked necktie and show her concern. Hasama also demonstrates his thoughtfulness by preparing a meal for Akane when she returns home exhausted from her daily activities. This gesture hints at the growing bond between them. During your time with family, you may have never experienced such lively conversations before. As their relationship develops, both Akane and Hasama begin to feel more comfortable in this new living situation. Akane decides to organize her bag discreetly so that Hasama does not notice any changes in her behavior. She is aware of the potential consequences if he discovers her true identity. The following day, after successfully completing a three-way interview, Hasama takes a walk around the school, reminiscing about his past experiences there. He eventually finds himself on the deserted rooftop, where two people reflexively hide from anyone who might pass by unexpectedly. The atmosphere of this place, known for its spear-like appearance, seems to influence Hasama's actions. Without any warning or explanation, Hasama's hands begin to explore Akane's body, particularly her buttocks. This sudden behavior may be a result of the mysterious and somewhat eerie environment they find themselves in on the rooftop.
