Tsuugaku Vector

So, Tsuugaku Vector which means "School commute Vector", really made me wonder of the meaning ever since I first heard it. It's the first song I sang to a guy, well, as what i remember, it's during the late February.I sang this song during our phonecall, if I recall, he sang two songs I think, "Twinkle, twinkle little stars" and the other one is Japanese "Junjou no Kanjou" I think.

Romaji lyrics
Kitai shichatte nemurenai tte kouiu kibun na no

Ame no hi wa kusege ni naru no
Sukoshi shinpai dakedo wakuwaku shiteru wa

English Translation
Is this what it feels like to be so excited you can't sleep?
I couldn't tell you on Valentine's Day or your birthday
We only ride the same bus on rainy days
I wonder if you normally ride your bike to school?
All the forecasts have umbrella marks: rain
Ruterutezuubo*
On rainy days, my hair gets frizzy
I'm a little worried, but I'm excited
I don't need an alarm clock
I can wake up so quickly
it surprises mom
My eyelash curler is perfect
School commute vector
I was so excited that I couldn't sleep, and I ended up sleeping in...
I brushed my teeth in a hurry and changed into my school uniform
It looks a little iffy outside
Light showers, that's not enough
Wait, the forecasts too? They're changing to a 50% chance of rain
Ruterutezuubo*
But when it rains, my hair frizzes up
God is so ill-tempered
I'm going back and forth
I steadily ate all of my breakfast
I don't care if mom is surprised
I brush my teeth one more time
Please let us meet...
School commute vector
WOW..
na..
But when it rains, my hair frizzes up
God is so ill-tempered
I'm going back and forth
I steadily ate all of my breakfast
I don't care if mom is surprised
I brush my teeth one more time
Please let us meet...
School commute vector

This song turned to be our friendship theme song, I never thought of that thing. Well, as how the title means, in my opinion, it may means about the ride the guy taking of when he's going to their school, or maybe it means that the girl excitedly wants to meet the guy to the school and hurriedly finish her breakfast to go there early. Oh my, seems to be more connected about us, since we hardly want to meet each other at school. Suits for our friendship, it's really a good choice for our friendship theme song.
Anyway, here's the different live performances of this song "Tsuugaku Vector", sang by Airi Suzuki, a performance where the whole group performed it, and the other one is when Kanna and Erika sang it in duet.
