Pink Lipstick
The bridal mask
City hunter
IRIS
Two wives
Temptation of wife

Recently watched:

Queen of ambition
Five fingers

~ThanksMuch~ Guyzz ;)) for all your recommendations ~ I so appreciate it... ..I'm also very much interested to watch TDrama & JDrama ~ if you know something... again ~ no Tragic & heavy drama ~ of course with a super happy ending ~ more of romance light drama ;)) ..as much as possible ~ the 2 main leads are the ones doing the revenge to each other (either one of them)..! ThanksMuch & KeepUp the Great work here in MDL ~!
Rooftop Prince was based on a revenge/murder-mystery plot, Autumn's Concerto had love>revenge>love but it is a melo, Personal Taste's main male lead had revenge as his motivation for success...
Try Ghost, but its cybercrime.
Innocent Man Can You Hear My Heart (sort of. it's a family melo w/romance) May Queen
