Both dramas follow a similar romance + business vibe where the FL falls hard, struggles, and fights to rebuild her life while the ML supports her growth in his own way.

Both couples make you believe in their love and story. The series are similar in the heart break you will experience, but is absolutely worth it. I am convinced that no other GL couples have fought as hard as they have for their relationships.
