It's pretty standard fare, as far as I can tell. The storyline wouldn't make sense in reality. But I don't think any Slap-Kiss lakorns really do; the whole revenge thing is pretty hard to get to make sense generally, but we watch it for the angst anyway.
Just keep that in mind for your expectations. Personally, I don't mind dramas that aren't realistic. I thought it was a decent show. Not my favorite, but I liked the angst involved. I likely will watch it again after a year or so, as I tend to rewatch things, but it might not be one most people would rewatch.
NOTE: This show is for mature audiences ONLY. There is a rape. It's not shown exactly, but if you are under 18, I wouldn't recommend this. Please watch some lighter shows that are age appropriate.
