I am a BIIIIIG Hello Project fan, so that's probably one of the reasons I loved this drama.

STORY: I really hate maths, and I didn't understand a single problem here, but it was actually fun listening to Nina's explanations when she battled the other girls. I loved Kazuki and Sayuri's characters, they were very friendly with Nina and Kazuki is like me when it comes to solving anything related to maths XD

ACTING: not that bad as I expected, since almost all the girls are idols and there are just a few who are actors.

MUSIC: I guess I don't need to say how much I loved Pyocopyoco Ultra in the opening and Hatsukoi Cider in the ending.

REWATCH VALUE: I guess I won't watch it again. I don't see why.

OVERALL: probably I should have given less than 8.5, but I love HP so why should I give a low vote to my girls? <3
