Looking for a Kdrama where the FL falls for the SML or some other guy, while all this time her true fate/love was meant to be with the ML. It can be like the ML falling/chasing the FL but she rejects while she chases after the SML who turns out to be a bad guy/wrong fit/rejected. Then the ML who always liked her, comes to her side and eventually wins her over. 

Not quite but close...

  • My Dearest - FL is planning to marry the SML who she has a crush on, the ML is chasing her and she keeps pushing him away, but ultimately SML ends up marrying someone else and FL falls in love with the ML.
  • Marry My Husband - FL is married to the SML who is a jerk, she gets a do-over via time travel and ends up with the ML who had a crush on her years ago.
  • Perfect Marriage Revenge - FL is married to the SML who is a jerk, she gets a do-over via time travel and ends up with the ML
  • At a Distance, Spring Is Green - FL has a long time crush on her childhood friend who is a playboy. She gets her heart broken, the ML steps in to help her, and she ends up falling in love with him.
  • Maids - FL is in love with the SML, they're about to married, and many things happen. It's implied at the end she stays with the ML.
  • Who Are You - FL is in love with the SML who she thinks died and is a ghost but he's actually in a coma., ML is chasing her, she ultimately ends up with the ML after the SML's death.
