I was so excited about this because I love the two leads specially HS, sadly it wasn't that great and struggled to not drop it.

Acting :
Ihave to be fair and say that acting-wise it was good, HS was spectacular, the only thing I couldn't stomach was the way Heyri was speaking, it's like a 3 YO child still I understand that it's the way she chose to go with the character so I didn't mind much, and while I like KH I couldn't see anything "in his eyes" the anger or calmness or whatever that he has to show was lost on me, I was only able to see one facial expression all the way, he just can't act with his eyes.
So aside from that I liked the rest of the actors even the annoying ones.

Story:
I don't know what was going on, and not that I didn't understand the story but midway it was all over the place, the way they showed she was not a serious case of DID then bam! She was cured just like that, I hardly could see her taking any meds nor was I convinced by the psychiatrist she was seeing and their conversations felt ridiculous.
Also I couldn't follow through the time, some days I'd be confused like shouldn't they be at work now or whatever? Are they allowed to take so much days off? Specially the days that HO had to stay with EH I and she sleeps for over 13 hours for like 3 days continuously.
Aside from lacking logic big deal, the story got very boring, the more you watch the more you get less excited to finish it, pity it was good at the beginning.

Overall not really bad, what I didn't like was personal preference, some can just not see the things I didn't like or can be easily ignored, yet I wouldn't recommend it to anyone unless you have patience and don't care much about logic ~
