I'm glad the actors were good, or I wouldn't have finished this series. The story was boring and the main lead lady was creepy.
Overall, I expected a lot because of the hype, but the series was a bit weird, too slow, way too sad and overdramatic... Luckily there were some cute moments that made it less heartbreaking.

My episode reviews:
Ep 1 was very strange
Ep 2 was even stranger...
Ep 3 got interesting because of the mental hospital
Ep 4 was weird and sad :(
Ep 5 was a bit cute with the sleepover :)
Ep 6 was interesting because of the spooky castle
Ep 7 was very dramatic
Ep 8 finally got romantic and cute, stockholm syndrome
Ep 9 started with a cute vacation, then it became too dramatic
Ep 10 was just sad :(
Ep 11 was very cuteeee :)
Ep 12 was plain rude! -_- overdramatic and then got too sad
Ep 13 was cutee then too dramatic
Ep 14 Sad. At this point I didn't wanna watch anymore
Ep 15 got psycho... and sad again :(
Ep 16 was actually a good episode and funny :)

I'd say if you want a better mental health drama, watch "It's okay, that's love"
And if you want a similar dark fairytale story but more interesting, I'd recommend "Black knight"
