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.
