First off, the rating I gave for rewatching value is low because the storyline is so intense that once you know what happens next then it's not something you want to see again. The appeal is gone? If you know what I mean. Also, I don't notice much about the OST.

Overall, the plot and acting makes up for everything.

Each episode got me so anxious and like everyone else here I binge watched this in one day. Seriously, could not stop.

Definitely the characters and his or her motives will have you debating on how far is too far between morality and societal expectations.

Give this a go, you won't regret it!
