Love the story line. The ending????? Such a cliff hunger. I feel like there is a second season. However, this drama was yet in 2015 and it's 2020 now yet nothing had been released. So I guess viewers just have to form their own ending. It would have been nice if there is a new season. To watch how life enfold for the brothers and how the psychopath been caught is more satisfying rather than thinking that they all had a happy ending.
