I truly don't understand the high ratings and popularity of this drama. The FL is one of the most annoying characters I have come across. Imagine a 10 times worse FL of Vincenso with most screen time, replacing the ML. Although she was given hilarious script but due to her abrasive personality, over the top acting and loud dialogue delivery, it made the drama barely watchable.
I for one would not be able to work with such a person much less than admire her. Her facial expressions made me annoyed most of the time.
The plot was nonsensical, full of loop holes and impossible to suspend belief, in spite of my best efforts. Many tough topics were dealt with crassness and no emotional depth. The ML was significantly disappointing as well with a limited range of facial expressions. I have seen him in few other dramas and he has disspointed me each time. There was no chemistry. Imagine leads who looked like in their late 40s acting as high schoolers (The FL was shocked after her first kiss). Her response to the confession of the second ML was beyond rude and uncaring.
All the side characters also displayed significantly poor acting skills. The only bearable side character was the second ML and the mentor of ML. You may watch it if you like some funny dialogues and can tolerate the characters after first few episodes.
