ML trying to get revenge on FL but ends up falling for her

I've watched Behind your smile, and now looking for something similar. Basically the ML is trying to get revenge on FL or someone close to FL while trying to use her and ends up falling for her. 

I'm okay with a naive FL but her character has to be likable. Looking for Korean, Chinese, Japanese and Taiwanese dramas. Tried watching Thai but they're too much for my taste. I'm new to this trope so you can recommend any. TIA ?
