I mostly watch Korean dramas and the ones that come to mind are :
Bad Guy starring the extremely talented Kim Nam Gil (I know it had some bad reviews but I personally really liked it and the OST is great.) + Innocent Man with the gorgeous Song Joong Ki.
Worth mentioning may also be Queen of Ambition. I recently came across a MV of the OST and then read some of the comments and reviews. It sounds good, has a great cast and hence has gone on my plan to watch list.
dramas: the princess man (recommend this one the most) innocent man missing you scholar who walks the night (even though it's supposed to be about revenge it became more of a love story and well, the main line has a lot of plotholes. Even though it's a great watch I wouldn't really recommend it if you really want a good revenge story. I'm still naming it though)
