That first classroom scene was gold. The shenanigans with the note-passing would be great in an of themselves, but in this drama setting they weren't as exaggerated so it felt real, and I loved it.
Mariko and Jurina in the same class.

Lol, the age gap between all of these girls being in the same class is so suspension-of-disbelief-breaking.
I think I ship Rena/Sayanee now.

But completely agree with gekikarabuACE, playful Rena was really fun to watch.
Oh snap, Yukirin can act! Did not see that much eye-acting coming.
Dawwwwww Takamina. GET IT TAKAMINA. <3 Her acting isn't immediately catching me like Yuki's, but like all things Takamina, comes off completely sincere and compelling for it.
The Oshimaeda scene: This is where the 34-minute thing breaks down in execution, because a full drama(or mini-series) would give us episodes of Yuko being peppy to give this mental breakdown more impact. Instead, we've been told not shown that Yuko's the mood-maker of the quartet. Similarly, previous episodes would establish what the OshiMaeda dynamic was like before the band and before the confrontation, so that we could see the changes after.
LOLOLOLOL JURINA HIGH SCHOOL GRADUATION. WITH MARIKO LOLOLOLOL.
What the fuck Kasai pregnant? What the fuck Saeboy? So fucking randommmmmm.
Heh, the strings they're using for the teacher's speech are like old PS2 synths. So cheap.
Aaaaaand so Yukirin's depression was magically cured, and everyone else found better jobs? What? And the school managed to buy a new set of drums with a fixed cymbal?
Ah well, don't care as long as Acchan and Jurina continue to wear those leather jackets. :d :d :d
ICWUDT with that "Onee-chan!" Aki-P. Make it easy for the fans to self-insert, eh?
