After watching Love O2O, I went in watching this drama not finding the male lead in this drama appealing.  That changed as I watched several episodes.  The chemistry between the two leads was amazing and won me over.  What I did not like were some of the over the top storylines and the sex crimes were taken so lightly, though I understand it's what grabs the attention of many viewers.

Overall, Memory Lost was mostly fun and interesting.  Wish the second lead had more expression and interaction with the female lead.

I'm not sure if it was trend of the times, but I found myself wishing the female lead was stronger and spoke up more. She was strong in what she endured, but required rescuing a bit too much in my opinion.

The child actor stole the spotlight and kept me interested in the story while the two leads frustrated me with their lack of communication and manic personalities (well his more than hers).
