Its just WOW!!!!💯💯💯 I give it a 100 points. This drama is going to be really unique, completely different from any psycological, thriller and mystery drama you have ever seen. The drama has really taken psycos to a real another level🤯. The story line is so realistic and good, you'll really be obsessed with the drama. I just can't imagine how the writer has come up with such a good story. I can watch it a second, third, fourth time without regret.This drama has got such twists and base story that on one hand where you'll resent the real culprit for his murders, on the other hand you'll try to understand the murderer and pity him based on how his living conditions were, when he was a child. He commits murder while being considrate of abused children but he can't understand that the way he is saving thme, its really becoming curse for the young ones. I won't reveal anything more, if you are free you need to watch it right away. If you dont watch it believing it wont be too good, you are really going to regret it.
