Mi-sun and Hye-kyo decide to go to a fasting house after gathering information about fasting food that is good to lose weight. Miseon and Hye Kyo write down their target weight and vow their victory at a fasting house that is a long way into the mountains. The origin of the singles' trainer, which emphasizes patience, emphasizes a regular life reminiscent of the army's quarters. In addition, they are nervous about the tremendous punishment of gaining weight or feeling solitary in case of violation of rules. Hye-kyo, who felt the limitations of a single fasting house with soybeans and cabbage leaves each day, did not overcome the temptation of the chicken that was put up for endurance test. When a friend of Tae-ran who came to the hospital asked him, Chan-woo likes it, he says. Tairan, who happens to visit Chan-woo's house, sings Chan-woo when the water is drawn to the sink. The moment they try to go out, they know that the bathroom door is locked and they are stuck in the bathroom. He is left with a friend's words, and he is nervous about the minor actions of Chan-woo.
