Synopsis: Monochrome Rumor

Hajin agrees to take care of Sihyeon's younger sister following a car accident that they were both involved in. However, Hajin wakes up in the hospital in Sihyeon's body rather than his own. Sihyeon was a notorious entertainer who would do anything for money, had countless sponsors, and was on the verge of leaving his boy band to sign a big contract with a bigger agency. Initially, Hajin believes the public's negative perception of Sihyeon, but as he learns more about his pitiful state, he becomes increasingly angry. Intent on avenging Sihyeon, Hajin seeks the aid of an old acquaintance. Nevertheless, as he delves deeper into his scheme for revenge, he becomes more involved with people.
