I don't think the writer have ever met an artist in real life or even know a single thing about art and painting.
The ML needs only 1 sec to judge a painting? Lol! Even Picasso wouldn't dare!

I loved Park Min Young in "When the weather is fine". She was pretty good in "What's wrong with Secretary Kim" but here the overacting was pretty bad. Not as bad as the FL in Vincenzo and Business Proposal though. Didn't care about the ML or the story. I liked the brother of the FL.

The only thing this drama accurately depicted was how stupid and embarrassing "fangirling" really is! I guess Korean people/writers are expert in that department.
