Randou Masashi is a brash karate star who strikes fear in everyone around him. But despite his intimidating presence, he is secretly in love with the sweet and beautiful Rina Kurimi. Unfortunately, Randou is involved in a horrific bus accident, which leaves him comatose and with a disfigured face. A year later, he awakes to discover something utterly shocking—his face now resembles Rina's! Randou learns that he has been under the care of a surgeon named Jun Manabe, who reconstructed Randou's face based on a picture he had of Rina. Moreover, Randou is presumed dead, and his parents have moved away as a result. Distraught, Randou crosses paths with Rina and is mistaken for her twin sister Yuna, who fled from her house two years ago. Although Randou initially wished to restore his face, seeing Rina elated makes him reconsider his decision. However, a boy disguising himself as a girl is as absurd as it sounds, and being surrounded by troublesome individuals only makes it more difficult. Nevertheless, Randou is adamant about concealing his identity until he finds the real Yuna. [Written by MAL Rewrite]
