Don't come now and do this to your little sister who didn't even care about you.
Jimin, now a successful Hallyu star,
and his younger sister, Park Yeo-ju.
Yeo-ju, however, ran away from home as a child due to her parents' discrimination. Her parents lied to her, believing her younger sister had died in an accident.
Yeo-ju encounters her on the street.
But Yeo-ju hates Jimin.
Yeo-ju tries to avoid them at all costs, and Jimin, feeling guilty, approaches her to apologize.
Will their ending truly be a happy one?
