A cute college drama inspired by the real life story of Jang Mi Ran, an Olympic gold medal winner for weight-lifting. Kim Bok Joo is a promising collegiate level weight lifter who has a positive outlook on life even though her family is poor. She and her good friends in the weight lifting club are not very popular with the boys and are in a rivalry with the rhythmic gymnastics team. Meanwhile Joon-Hyung is a talented swimmer, but seems to have false-start anxiety and complications when it comes to the real competition. He decides to go into therapy in order to resolve this problem.
One day, these two athletes end up bumping into each other and find a familiarity in each other’s faces. It turns out that in their childhood, Bok Joo had saved Joon-Hyung from a fall. Thus, the two strike up an unlikely friendship with much teasing from Joon-Hyung’s side. For Bok Joo, she ends up having a crush on a weight loss doctor that she met on the streets and that had treated her like a lady. She has always been self-conscious that her sport made her seem manly and Dr. Jae Yi treated her differently. Thus, she decides to sign up for his weight loss program so that she is able to see him more.
However, that is in conflict with her competitions as she is suppose to increase her weight to enter a new weight class. On the other hand, she wants to be praised by Dr. Jae Yi for losing weight. Thus, she starts to lie to both parties, the weight-lifting team and the doctor, about what she is really doing. Furthermore, by coincidence, Joon-Hyung is actually the cousin of Dr. Jae Yi and her double life comes to a head when he finds out that she has been going to his clinic.
