Taking his wife to the gym was a very wrong decision of the husband, he just wanted her to have a slim and fiery body like other women but did not realize that it was the catalyst for arousing the desires of other men, typical of the gym owner in the movie. After going to the gym for a few days, with the enthusiastic guidance of the trainer who is also the gym owner, her figure becomes more and more attractive, but at the same time, this is also when the gym owner shows his lustful nature and gradually they develop feelings for each other. Then they enjoy each other every day behind the back of the unfortunate husband who still believes she only goes to the gym.
