A romance drama about two female high school students who happen to share the same name. When they both transfer to a new school at the same time, hoping to use the opportunity to turn their lives around, they forge a secret contract to swap identities. Shin Yi Joon is the most popular student at his high school. Although he seems tough and aloof on the outside, Shin Yi Joon is actually a huge softie on the inside—and far from getting into fights with other students, he even has a hard time saying no to other people.
