This is my first drama review ever, so I hope I'll be able to express my opinion as clearly as possible :)

The story is not too complicated once you get into the first couple of episodes. It's very nice to see the FL and ML relationship have their ups and downs. There were episodes that were heartbreaking to watch and others that were pure joy.
There are like always some holes in drama storylines (from my experience so far) but this drama barely had any. That's why I found it easy to follow and not be confused about the relationships everyone had with each other.

One thing I really like is the FL's strong character and will. That's probably why I liked her since the beginning. She's someone who does what she believes in and doesn't give up. She brings out the ML out of his solitary place and could be seen as his 'saviour' (why always the ladies though? xD).

I think I continued watching more for the characters and their relationships with each other, than the actual story lol. I liked the fact that all side characters were strongly present and that they weren't warm from the beginning (which added credibility).
The beginning might be confusing, but if you search for a drama where the ML finds a "robot" (person in disguise) who helps him bring back relationships and people in his life then why not give this drama a try.

Thanks for having read my review, I'll try my best improve my review writing skills and I hope you liked or will like the drama as much as I did or maybe even more ;D

PS: The scenes with foreigners always crack me up, and I don't know if it's the suddden English or the fact that they always need to be pretend to be either from the UK or US
