Momoe Omori (Rio Uchida) and Ken Matsuda (Yuta Koseki) have been trapped in the company's underground warehouse. Can the two who barely keep reason overcome their sexual desire !?
On the other hand, a mistress and heart (Chika Nakagawa) who is embraced by various men every day. She keeps smiling at any customer, but she imagines that she is in her heart when dealing with unpleasant customers ...?
In addition, Momoe is depressed in her empty life. It was one of the saffle, D-kun (Kentaro Tomita), who made me forget her feelings. D-kun is a freeter and has no money, and he is a little stupid, but Momoe is cheered up by the brightness.
