Ok, so I after finished S1 I came here and the ratings and reviews scared me lool
How it was possible? S1 has 9.1 and this season review where so negative I was confused but now after finishing the all thing I see where people are coming from.

The biggest problem here was the lost memories plot. It took 8 episodes out of 10 and the revelation was dry asf. UK didn't seemed the surprise or happy at all. They dragged the drama so much. 5 episodes would be enough.

The filler with So-I was unnecessary, Yul almost dying because he was too guilty to ask for help didn't maked sense, plus he was planning to kill Naksu, the same friend he was guilty of leaving behind, I just can't understand really.

Every episode a new theory would pop up about Bu Yeon's soul, one episode it was gone and nnext episode it was still alive it was annoying and confusing.
The comic aspect was also gone ?1 or 2 jokes sometimes, but It was forced sometimes.
Bu Yeon's mom was a B, but they made her somehow a better person at the end LOOL

I really think they should wasted more time in showing Naksu's new personality to the public, she kinda lost her badass and rude attitude that we loved, the mannerism was there but still...

I'm not even mad at the change of personality I'm mad that they wasted her character, in my opinion she is living as BY and not as Cho yeong. It would be nice seeing her still as a skilled warrior with BY's supernatural powers, a mix of both. It would be better in my opinion. Her character in this season was just a love interesting of Uk, that was sad for me.

At the end she didn't fight along side with UK and that was disappointing to watch. Just another weak female lead at the end.
