Both are historical dramas in which the girl works as a maid in the palace and falls in love with a prince. Both dramas are full of drama and political intrigue.
They are both about the same story. Scarlet heart is the drama that is more intense. A time to love is the movie and is a lot more light hearted. Both are tearjerkers though.
