Welcome Rain to My Life

The series revolves around Han Dan-bi (Lee Da-hee), a rude woman who was raised in a wealthy family. Her life becomes difficult after her father, a once-popular singer, meets with an accident that was planned by his wife. Dan-bi then finds out that she was adopted. Her stepmother takes advantage of her husband's comatose state to kick Dan-bi out of their house, all in a plot to sell his land to the ruthless chairman of a hospital company.

This revelation leads Dan-bi to begin searching for her birth mother by using her adoptive father's will as leverage, not knowing that the truth about what happened to her birth father is directly tied to the chairman. She encounters several people along the way: the chairman's grandson who falls for Dan-bi but is uncertain of the outcome if they became a couple; a divorced lawyer whom Danbi loves, but whose father is also connected to her birth father, which is the reason why the lawyer's mother disapproves of Dan-bi for her son; the lawyer's ex-wife, and their daughter who likes Dan-bi more than her own mother; a step-sister who sees Dan-bi as a roadblock to climbing the corporate ladder; and an ailing doctor who was not only the love of Dan-bi's adoptive father's life, but knows the real truth about Dan-bi's parentage.
