if you're here for the romance...i don't know what to tell you. other than, prepare for disappointment. Heo Yi Jae (FL) is not a good actress. like she's crying and there is no emotion on her face bad. Hyun Soo is extremely poorly written. Ma Doo Jin (ML..maybe? it's debatable) isn't much better as a character but actor Cha Do Jin brings a better performance (but not by much)

the reason to watch is the revenge plot. that's where all the great characters and great performances are and it's really the driving force of the show. honestly with a little tweaking they could have nixed the romance altogether and had a show i probably would have given a 10. i felt it was wrapped up well, though i was worried for the last 10 eps that they were going to pull something stupid.

Shim Ji Ho is stellar in this. i wish he got more serious roles. he would slay.

if you like a daily dramas and makjang and you're willing to look past some flaws then this is worth the watch.
