I found this drama slow and boring. I found that I was more interested in what was happening in 2015 then in 2007. The male lead is a typical cute boy who bullies the female lead because he likes her but won't tell her. The female lead is the usual shy, naïve girl that does not do anything bad but always gets in trouble. The female lead annoy me because I felt that half the time she was space out, and as cold and stiff as a light pole. When they said she was crying I could not see it or feel it because it look so fake and her eye did not even seem wet. I could not understand the relationship with her parents. Yes, they were strict but they seem as they had no feelings for her. What happen to motherly love. Especially she is their only child. Her house seem more as a detention center then her family house. The principal seem as he was constipated, that is the look he constantly gave. The man could never crack a smile. Maybe he needed to fart. The army sergeant had more understanding of the kids and was more relatable to the kids then the principal. The story did not make sense and I thought the back and forth was worthless. The script writer especially needed to read his own scrip and make it work and the director also needed help.
