Not what you would expect from a drama that has main story a mom who goes back to school. Actually, the whole silly comedy that one would have expected is easily dashed out by the first episode that is a shocking bullying themed episode full of drama. The first half of the drama, actually, exploits that theme, until the politics kick in. And sure, the whole corruption theme is entertaining, but not something that you haven't seen before. Still, it was okay, with the performances excelling in every way by every one. Finally, I have to point out the egg thing. There were several scenes with eggs breaking or falling and crushing on the ground. I don't really know what was the meaning behind it but they just kept showing it. So, 7 out of 10. PS Seems like Jisoo will never break his second lead curse ...
