Geon is a personal trainer in desperate need of new clients or else he'll be fired. So when he encounters the overweight Gyuwon decked out in designer brands, he sees it as a golden opportunity. Unfortunately, this comes at the cost of heeding Gyuwon's request to go on a date with him once he achieves his dream body. When Gyuwon transforms into Geon's ideal type a year later, Geon finds himself slowly drawn to him. Will Geon be able to resist the seemingly perfect younger, rich, and hot guy? Or will he succumb to temptation and fall for him? (Source: Tappytoon) Note: Contains three side story chapters.
