"I want to fall in love again. I want to be seen as a woman..." The pure feelings of a young wife whose husband no longer sees her as a member of the opposite sex... Such is her adulterous trip to a hot spring that she visits only once every six months. A kiss right after the reunion... masturbation in the open-air bath... hunting for men at the hot spring resort... Unusual sex with someone else's wife... it was a very dangerous chemical reaction.
