At a secluded hot spring inn, a brothel steeped in centuries of tradition since the Edo period thrives on desire. This scene takes place just after a session at the hot spring soapland. The scent of cypress fills the air, the soaked floor holds a soap mat, and used condoms scattered about catch the eye. Amid it all, Manami Chihiro, a graceful and virtuous married woman, stands fully naked, cleaning the bathroom with a sorrowful expression. She picks up condoms, rinses the mat, scrubs the bathtub—quietly carrying out the cleanup with a heavy sigh. Behind her lies a deep, hidden truth only revealed within the secret baths of this hot spring. Here, concealed within this tale, is the tragic downfall of a once-chaste wife.
