I would say I liked the second season a little bit better than the first one.

Really really love the casting. I don't know why but every time I see Lee Sungkyung, I always imagine her perfect role as a rich snobbish girl or a doctor. Those roles really suit her. She and Ahn Hyo Seob have really good chemistry!!! However, I might say that the romance side of this drama was weaker than the first season. I was hoping it would've been highlighted a bit more.

The only thing I think was a problem for this season was they were trying to fit a lot of stories and plots into one season: The trauma of Cha Eun Jae, Back story of Seo Woojin, Park Gyumin's backstory, the illness of Master Kim, the evil plots of Chairman Do - to name a few. I think if they could've extended it to at least 2 more episodes almost everything, if not everything, would've been addressed better. The phasing was a bit too fast for the important parts. Especially the last episode, it seems like they just tried to put as much as they can to close the book.

Also, I wished they could've done more crossovers with the characters from the first season.

But still, really interesting and worth the watch!!!
