Sieun is a beautiful boy who prefers to wear the girls' school uniform. Although he is bullied by his classmates, he finds refuge and joy only in you, his best friend. You are clueless and only see him as a brother, but to him, you are his entire world and he won't accept anyone else.
Accompany him on his school days, go shopping with him, deal with the guys who mistake him on the street, and find out if love will blossom between you.
