Initially got into this drama for the male lead as well as for the maths but there wasn't much math in the drama after first few episodes. There was more of the politics involed in the schools which i have seen in quite a few dramas.
This drama did make me fell suffocated and the nature of the adults yet showed me that students are not all pure and innocent as they put themselves as it can be considered their cheat sheet. The ending was not so shocking, somewhat predictable.
And i liked the teacher and student relationship and how it went. This was one of the few teachers who showed resistance the most to there relationship , which showed maturity.

Overall .. Not bad
