If you don't really have time to watch every drama that's coming out and you're considering picking one or two to watch, I def wouldn't recommend this one just isn't worth your time. If you have free time though, sure go for it. If you're willing to invest over 32+ hours in a drama filled w cheating, go for it.

The plotline's pretty unique imo considering the fact that the writers came up w 3 different cheating scenarios for the 3 main couples. I like how they're all connected by their workplace. If you're wondering, yes you MUST watch season 1 to even understand what's going on as the plotline just continues off of the first season. It's alot of investment.
