After Yeonju left Eunsung for the sake of his success — despite loving him deeply — she later discovered that she was pregnant.
Ten years later, now the mother of Hanbyul, Yeonju works as a stylist, only to find out that the lead actor in the movie she's working on is none other than Eunsung.

He thought he had moved on from his past feelings, but now, more desperately than ever, he realizes she is the one and only love of his life.
