After watching few episodes from this drama
I was enjoying much and I was going to rate it high till ep.09

starting from episode 10 everything were in mess
The characters development were under zero
Women's character in this drama were divided between
Naive , frustrating and selfish B****, annoying

The story wasn't good enough
many events were illogical
The plot was ok
The romance was lukewarm
The villains were extremely annoying
The FL character were depressing

And the punishment for the villain characters were weak

What happened to yoon joo and the FL'S sister weren't fair enough for what they did
And they continuing selfish B**** as they were till the end

The FL continue naive and weak till the end
Jung woo the professor was too loyal for such a great B**** like Yoon joo

Something went wrong after ep.09 which made me lost my interest and took a deep breath after I finished it

6/10 just for seung heon because I'm big fan for him
His acting is superior really
Inspite he was smiling most of the time when he looks to the FL while they were talking seriously
Which made the acting lost it's credibility
