Had a good time watching this drama...there were many cute scenes and the acting was pretty good. ML was also good at acting (you can really see the difference before and after his psychological issues). They also had a good balance of silly characters that didn't go overboard. Also love that the FL and SFL are both smart kickass women (yah, its possible for two queens to be friends). One thing I found interesting was their use of many side characters (it didn't distract from the story but I feel like there is usually a more limited cast or larger side casts are usually all in the same area such as the workplace in c-dramas). I think the only real negative thing I can't justify is her reason for pretending the ML is her fiance (the original lie that started it all), especially as I don't think she actually liked him at that point, so there was no straightforward benefit for anyone from that lie. If it made the checkout process (leaving the hospital and Thailand) easier, I think it should've been explained (but you usually need your own ID anyways and that point, there's no difference between a good friend and a fiance).
Overall, the storyline was original (although the plot was quite predictable and had some classic rom-com tropes) and I liked the chemistry. Story didn't feel too draggy at 32 episodes, although I think quality wouldn't go down if it was 26 episodes.
