The opening song is so good. Well, since the girls are idols, they are cute.
The story is like students become detective to search the one who killed thier teacher. So, kinda weird one but funny and interesting story although it's a drama of japanese idols who have no acting experiences. I like some plots and how they ended the drama.

Worth watching. I will try to watch it again later.

Btw after I watched this drama, I searched info of their group and found out that their songs and performances are pretty awesome. Now I think I am a fan of them already LUL.
