Another drama that I highly recommend to be watched. The story itself is interesting, it keeps one attention the whole time and one cannot help but take sides. 

Good side or bad side?

Is the good person really good?

Is the bad person really bad?

I won't give out any spoilers, as I will let you be the judge of that. The human brain works in different ways and sometimes we tend to justify the reasons for doing something. 

Enjoy!
