Himari, who lives happily with her boyfriend with marriage in mind, is traumatized by a terrible ex-boyfriend from the past. One day, something unusual happens, such as things moving around in the room and money disappearing. When she consults Ichiro about it, he tells her it's probably just her imagination. Himari thinks she's mistaken, but sets up a security camera just in case, but finds the room ransacked and a letter left behind that says, "You can't escape!"
