I JUST DON'T GET IT! 

I don't really get the idea of the Happy Birthday PV, honestly, I just don't understand it~ 
what's with those paper models? seriously!
The song is cute & catchy & it just saves the whole PV! oh and my love for the boys, too !! 
what's more disappointed?
- the position arrangement is lame!! Tegoshi standing between Koyama & Pi --> how stupid!! Tegoshi looks like he's only 150cm ...ZMOG
- the animated shapes make me feel like it's a cartoon for children or sth (my niece would love the PV more than I do for sure!)
- a bit too white!
- member ai ... ... ... ...

on the positive sides:
- is it just me or Pi  smiles very brightly in in the PV?
- Koyashige XD~~
- the dance is cute , fits the song well
- the "Happy birthday to everyone" scene is LOVE!  ("ima wa" & Pi's cups XD~)
- Massu's cute as always
- the boys still stole my heart even the PV itself is not so good
