CONS:
*2nd and 3rd episodes where way too slow
*plot was so annoying at times I almost dropped
*songs sometimes feel out of place

PROS:
*the "good" parts are way better than average dramas
*acting is great, especially In Guk and the butler
*likable cast of characters (them ajummas)
*hilarious comedy
*great song choices (Monster X, GFriend)
*mostly good pacing
*very lighthearted (finally!)
*rich son that's not a douche (bless)
*not many flaws in plot

Overall one of the better dramas out there, would totes recommend
