Which K-drama do you think's  the best jealousy scenes? My top is Boys over Flowers.

This one is tough. I am not sure which one is the best, but I really liked a couple of scenes in Go Ho's Starry Night and the noodle triple date in Fight for My Way. If I was to choose, maybe the Heirs had the best jealousy scenes? The pool and the school fight scenes were pretty good.

i liked the jealousy scene in Mary Stayed Out All Night

kim bok joo one  of best jealousy scene

In The king2Hearts I still can't forget what the male lead did to the female lead just because she was playing and smiling with the other guy.  He elaborated a whole plan and played with her feelings just because he was jealous xD I hated him for that tbh he was immature and petty.
