Short: Bullying in school, corporate and political crimes, all come to a head when the Mothers get involved. Good story with some fun moments, I enjoyed the ride and I was happy with the ending though it did seem like a couple of smaller points got skipped over it didn't spoil it. I don't think it'll be the best drama you ever watched, but it will be among the better ones :)

Detail:
34 year old mother poses as 18 year old student and enrols in school, nobody bats an eyelid. As long as you can get over that, you'll do fine - and it does create some amusing moments such as when one of the students starts liking her :)

This covers a range of areas with similar themes whether it's abuse, bullying at school, political crimes, slush funds, conglomerate chairman crimes - it's got them all. It unravels itself bit by bit as the mother tries to do her best to protect her daughter.

One of my favourite characters was Han Gong Joo, played by Go Soo Hee - she has a completely different and always over the top fantasy princess dress on every single time she's in a new scene, everything's over the top for her but she's a solid character overall - it would have been easy to overdo it and for it to go wrong but I think her character was done very well indeed.

Difficult to pick particular issues with it, other than the base premise being a stretch (but aren't most?) - though the fake brick wall at the end was so badly done it was hilarious. It's good light hearted fun that plays on numerous old school formulae, enjoyable to watch but probably won't be at the top of your rewatch list (though... it won't be at the bottom either, for sure).
