Firstly the drama started with a banger episode, it was intense and let me clarify, I hadn't seen the trailer before starting so, I was super excited when I saw Jang nara n Son hojun together again though that took a very quick turn.
The first 4 eps are really good but the drama somehow lost its direction after that but those who like crazy, unpredictable plots, might actually love it. After that from 10th episode, it was just total madness. I still get frustrated thinking how they were just hiding their feelings and hurting each other.
I get why FL was frantic but there was no reason for Soon Young to act crazy and do all that nonsense, even till the last moment, it didn't make sense for why he did that -_____-
Lastly, the ending 3 episodes were kinda slow compared to how crazy the plot went.

Don't believe the plot synopsis given, its deceiving, but if you have lots of patience and really are a fan of psycho, thriller, suspense with toxicity, then you should give it a try
