Ho-kyeong, Joo-yeong and Yeon-hee are students of an American university who are all pretty and sexy. They either know too much or know too little so they decide to find men who can satisfy them. A lean man who was a former nude model, a younger man who has perfect techniques and a man who thinks very highly of women; these guys start the project!
Unfortunately the movie Mutual Relations is not yet available on HBO Max.
