Sakura, known for her airheaded personality, orders pizza delivery at home. When paying, she spills her loose change while chatting with the delivery guy. As he watches her bend over to pick it up, he catches a glimpse of her braless chest, making his heart race—though he tries to hide his excitement. Unseen by them, a suspicious figure lurks, peeping through the door crack. The next day, Sakura orders from the same pizza place again and once more drops her coins. But this time, the delivery man's behavior seems clearly off. Sensing something strange, she begins to feel uneasy about what might happen next.
