When I started to watch this drama I suddenly remembered another Colombian serie called "Ellos las prefieren brutas". It was so much alike that at first I though it was a copie from Personal Taste. It was exactly the same until episode 6 or so. Neither of them was memorable, but just until there it was more or less ok. From there, I don't know what the screenwriters were thinking but it was boring, illogical and with sooooo many tropes... So, if you have ulterior motives to watch this (Lee Min Hoo?) you can watch until episode 6, the last 15 minutes or so of episode 10 (perhaps the "Game over" scene could be the most memorable in all the show) and the last episode if you need to know what happens at the end.
The rest is not necessary. The role of the second leads is soooo flat... They are 2D, no development nor coherence at all and their stories are boring too.

Acting: I decided to watch it for Lee Min Ho (though I have to admit that I can't think of him as a good actor after having seen him at least 4 times already). He could have done much better. I think he was slightly better than in Heirs, but anyway, his role was boring. I didn't like very much neither the female lead, her role was too childish, she cries a lot and on the other hand, how is it possible that she works with so dangerous tools but she is not capable of picking a broken cup without cutting herself a finger?? Incomprehensible!

Music: I didn't remember, so I suppose it wasn't memorable.
Rewatch: as I saw before in another review for this drama in MDL, why would I do that to myself?
The better in one word: the house Sanggojae.
