I can't give this drama anything but a 10/10 because for its style it was perfect. It was almost exactly what I was expecting.
Whoever is in need of a light comedy should watch this. Expect many hilarious moments. Nagase Tomoya is very expressive, you'll most likely burst into laughter at the mere sight of him. However, expect some depth too. They handle serious matters as well: redefining one's life, learning about true love and friendship, surpassing one's limits. These are all expressed very well and they transition smoothly into and out of the humour. You'll find some very touching moments too, but that's definitely not the defining theme of the drama. It's almost entirely comical. And despite basing itself on serious matters, it manages to stay light enough to be enjoyable as pure comedy.
Acting: I was quite surprised actually. Given the obscurity of this drama I thought they would probably have a bunch of mediocre actors, but these kids are brilliant! They exceeded my expectations. Almost all of them anyway.
Music: It was SPLENDID. I fell in love with the ending theme from the very first second. And the music throughout the show is also very entertaining; it goes well with each scene and just lifts your spirits. For a pretty underrated drama, the music was exquisite. Too good to ignore. It wasn't just a soundtrack, it was a lot more powerful. In some scenes my attention was actually stolen by the music than the action.
