Mystery stories happened within the rich families who live in one building/compound. All have different stories to tell but all boils down to a mystery of few characters.

For those non-romcom fanatics like me, these are the 2 crime/thriller Korean drama series I can highly suggest.
Both having the storyline of investigations and very interesting cases, I just got hooked on to these that easily.
So, if you are looking for more intensifying scenes and climaxes, these 2 are the best for you! :) I hope you'll have the same thought as mine after watching these.
