A GOOD THRILLER REVENGE STORY ( NOTE: NOT A ROM-COM AS SAID IN TAGS !)

I'm still wondering why there is a comedy tag placed first for this series, I thought it would be a com
revenge story but except few scenes there was no comedy in this , STOP misleading watchers with the tags.
Anyway other than that it was good gripping series which keeps you on edge almost every episode with good story line.
Kind of similar concept to perfect marriage revenge but different kind of story. MUST WATCH ATLEAST ONCE.
