The main leads can't be together for some dramatic complications

Hey all I just found out this about me!! I like the dramas where the female lead shouldn't fall in love with the main lead because of some dramatic complications, but she still falls for him I found this out after watching "When a man in love", so I'd appreciate a recommendation for something similar and with a happy ending please... :D
