This is just my personal opinion, but I came for the romance and stayed for the plot. I read a lot of crime, mystery, suspense, thriller, detective, psychological and horror stories so a drama with almost all these elements really hooked me! (Note I said almost)
There are a lot of plot twists, but they aren't the frustrating kind. They actually leave the anticipation for what comes next. And the visuals are amazing...
I do feel that some scenes have been repeated a bunch of times more than necessary. I feel like they do it to remind us what the purpose of this drama is, but I got used to it and I'm pretty sure that defeats the whole purpose XD
A lot of people said there isn't enough romance, and tbh idgaf because I'm too into the story. Again, this is just my opinion.
The shorts at the end are so cute and they're like a break after a heavy episode. A wonderful drama. Definitely recommended!
