START-614 — A beautiful office lady who is newly married and trying to conceive is brainwashed into believing that the man is her husband and then has unprotected sex with him. (Miyajima Mei)

Newlywed and trying to conceive, the beautiful office worker Miyajima Mei has her consciousness rewritten by her obsessive colleague Kashiwagi using "earphones." Believing herself to be Kashiwagi's wife, she mistakes him, whom she should have hated, for her "beloved husband," and submits to him with a lewd expression. Before trying to conceive with her husband, she seeks Kashiwagi's seed and becomes addicted to unprotected sex—a record of a depraved alteration of her personality.
