Love Triangle drama

Hello, I'm looking for Korean or Chinese drama featuring maybe a love triangle. So the story plot is something like that. Female lead likes male lead from the starting but he doesn't responses to her feelings or doesn't cherish her or they just part their ways due to circumstances. Later on female lead starts to date or maybe marry or like be in a relationship with the second male lead and this ignites jealousy and desire in the mind of male lead to Get FL. He starts to develop feelings for the female lead and he starts to chase her and woos her constantly. Something like of these dynamics. I already watched Jealousy Incarnate and Summer desire.  

IT IS IMP THAT THE FL REALLY BE IN THE ROMANTIC RELATIONSHIP WITH SML. I want modern romance drama only
