Nagisa Umeno

Natsumi est obligée de travailler dans une usine pour payer ses dettes. Cette usine est connue pour employer des femmes aux "sombres passés" pour accomplir des tâches peu recommandables. Tsukada, le chef de la sécurité place Natsumi dans une équipe de 4 femmes dirigée par Atsuko. Quand l'une ne fait pas correctement son travail, Tsukada la viole et Natsumi est la prochaine sur la liste...

A man thinks he is an actor. He has a part-time job and likes a cute girl at work. He grabs the chance to have sex with her. Premature ejaculation hits, however, as he is taking off his pants. Angry at what has occurred, he decides to train in order for this not to reoccur. He shares an apartment with a friend. The flat-mate is going to help him with his training.

The two are friends. The two are parents and children. The two are lovers. Being together softens my heart. I'm glad to be with you. And lonely. The loneliness that I only feel when I'm with you.
