Great Jung Kyung Ho, I like this actor. It comes across as authentic and grandiose especially in the monologues.
What I think was missing is the couple's chemistry (I didn't see them together well).
The plot and OST of the series are nothing special, but several serious questions are raised. For example: defamation.
People who, with their judgment, raise or lower their thumb, changing people's destinies. In this case, these terrible meddling mothers who even stick their noses into the professor's private affairs. But with what right, I say!
The bad thing is that unfortunately it often happens in the real life of Korean VIPs.
Another problem is the "survival" of students at school who are subjected to strong pressure from their families and have to face tough exams which leads them to exhaustion and some even to suicide.
And finally, a life lesson: be careful about placing too much trust in people. You can never say you know someone well.
