Hi 

I want to watch a drama with a similar plot like (When a Man Loves) 

I  mean he loves the girl but she doesn't like him.

and I want to watch a good drama like [Golden Cross] ~ revenge


Monster (2016) - the female lead doesn't like the male character in the beginning; it also focuses on revenge

Other revenge based dramas that you might like:
Defendant
Brain
Gap Dong
Zeni Geba
