If I love, It's unrequited!

Saebyuk falls for Kyungi, a high school girl he sees every day at the bus stop. But his love goes unreturned—and because of his rare hormone disorder, his unrequited feelings trigger a change in his body, turning him into a girl. Strangely, Kyungi starts showing interest in Saebyuk now that she’s a girl, and the two grow closer as friends. Will Kyungi still like Saebyuk if she knew the truth?
