Kou Kou Kyoushi without a doubt is probably one of the better dramas I've seen. It's one of my favorites and I wouldn't mind re-watching this. The story was pretty good, the acting was great, the music suited the theme of the show, overall it's a pretty good show, if you don't mind dark themes. Even though it's one of my favorites I'm not going to act like there is nothing wrong with this show. The first thing I thought was odd with this show was how obsessed Mayu was with the teacher when she only knew the man for less than 24 hours! She was saying things like "I'll protect you", stalking him, etc when she barely knew him! Speaking of Mayu, I personally thought that she was too good for that teacher! Sure they make a cute couple, but there were times I just wanted to slap the teacher for the things he would say or do to Mayu. Another issue I had with this show was how the students could bully their teacher, throw acid at people, etc and face ZERO consequences but if condoms were found in their school bag they got expelled, and the way the girls act towards their male teachers was cringe worthy! There are more things I wanna say, but I don't wanna post spoilers~ Now what really made this show good, was how there were moments that melted my heart and had me in tears. The actors did a really good job, especially the people who acted as Mayu and the gym teacher. The romance in this show was pretty sweet and much better than most romantic dramas I ever seen, you could actually feel how genuine the feelings between the teacher and the girl is. I also loved how moments in this show had me really thinking about all sorts of things, and always had me wondering "What will happen next?" This is one of those shows worth watching at least once.
