Sohee and Xiumin are twins, though Xiumin is a minute earlier than Sohee. Xiumin takes school in China and lives with the father, while Sohee takes school in Korea, and lives with the mother.

Sohee gets into an accident and has to get surgery, Xiumin take her place in school, and meets a someone he can't love.

THIS CAME FROM MY IMAGINATION, IF SOME PARTS/CHAPTERS ARE LIKE FROM OTHER FANFICS, IT'S A COINDENCE.
