Ryo is a bank employee whose life runs on strict routines and total control. Her husband left six months ago because he could no longer bear being managed in every detail, just as every man before him eventually told her he could not keep up. On the very day his divorce papers arrive, she catches a young adult man breaking into her home to steal underwear. To her, it feels like fate has delivered another man for her to control—so she locks him up for three days of restraint, forced ejaculation, and fetish reconditioning.
