Good drama, better than expected, full of real characters [teachers and students] you feel are genuine people and you really want to know what happens to them. What a sweet temperament Lee Hyun Woo has. Ep. 10/11 - so far as math's concerned you could say this one went off at a complete tangent. I suppose you have to have "plot development" but the romance angle frankly bores me and I went off watching - back now and it seems to be picking up. On the + side, that director woman is wonderful - the way she can pack so much comedy into just saying "Bo???" is priceless. Ep. 14 and the floodgates of emotion burst open as the high point of the drama approaches. Overall, despite losing its way a bit in the middle, this has been a good drama, good idea, with personal stories interweaving in a mostly not too intrusive way. Probably more episodes than could carry the weight of the idea - I usually feel that conclusion when I stop watching for a while, interest flags but picks up when you watch again - well. I did and they were really tugging at your heartstrings with non-stop emotion and tears in eps 15 and 16. It was not a totally predictable ending. It was wrapped up pretty well with everyone staying in character (including Chan Doo's dad). You felt for and lived with these characters by the end. If that's the test of a good drama, it passes with honours. Very hard to mark this one as there were flaws but overall it caught you up in the story and characters.

Story - the premise is not that original, though in this case it was done very well and the way it was told and the characters (especially teachers) were original. Rare for me to watch two episodes one hour long in a row but I did here. The bit right at the end brightens you up after a lot of emotion.

Characters - brilliant

Music - some of it got on my nerves tbh, especially the folksy music and "fighting" music.

Re-watch - A hard slog this course of study to through again. Also, when you know how it comes out it loses the dramatic tension towards the end. Not one to re-watch for me but recommended for others, it's worth sticking with. My overall rating may seem illogical given the others are sometimes low, but reflects the good parts that really got you involved - the sum of its parts were better than the individual categories.
