It was really good and I liked the ending because it wasn't plain and generic. but yoon sus death still got me fucked up and I even started crying. he was such a good character and I wanted him to survive until the end T-T.
such an amazing psychological show :) You have to pay attention to understand the mc. the acting was also so good and the ending was SPECTACULAR... I'm probably never going to find such an amazing series about human emotions and how you can break someones mind.
