One of the most fantastic k-dramas I have come across. While season 1 majorly caters to the suspense behind the brutal killing, Season 2 takes you through the emotional journeys of each character. It gives ample of space for each character to shine and dwells into the grey areas between the wrong & the right. In the end Season 3 will leave you satisfied, the last episode will make you miss the characters the more but it will bring a realistic end to each one of them through the upheavals from the season 1.
