Female Lead moves on from Second Male Lead

I want to watch a drama where Female Lead and Second Male Lead were a couple. Then SML hurts FL badly. She takes her time to move on. In the process of moving on she meets ML who slowly falls for her and loves her unconditionally. ML can be not so attached with others but with FL he is completely different. I want it to be hate-love type of a story where ML and FL start off as enemies and then ML falls for her and head over heels in love with her. She takes time to fall for ML.

Thank you for the recommendation. I have already watched this drama. But I want a drama where SML hurts FL. And she tries to move on, at that time she meets ML and they have sort of hate-love kind of a relationship with ML falling first. And finally she completely gets over SML and loves ML.
