|-|Approved English Lyrics=
Feel it cutting into me, that doubting painful knife
Stabbing a vein at the end of it all
Sickly love spurts out
Even my Les Paul became a deadly weapon
It's no-fiction
I like Math and Science
But I was never one for Japanese
I'd worry about which answer was right
Jokes on me, both were wrong
Today's homework is my basic self
With just enough, with no complaints, living in the nowadays
But why do we sometimes—no, always
Say we're sad? Say we're lonely?
Can you read the kanji on the board?
Can you read the shape of her heart?
Who stained that heart black?
Who was it? Who was it!?
Can you do this problem on an abacus?
Can you undo this collar on her neck?
Can we keep going like this?
What're you gonna do? I don't care anymore!
All this time we were
Under a crude hypnosis
Holding an incredible arrogance
Hidden inside
Can't do yesterday's homework, as always
With just enough, with no complaints, living in the nowadays
But why does this lump in our hearts
Say we want to disappear? Say we want to die?
Can you read the kanji on the board?
Can you read the shape of her heart?
Who stained that heart black?
Hey! Who was it? Who was it!?
Can you do this problem on an abacus?
Can you undo this collar on her neck?
Can we keep going like this?
What're you gonna do? What are you gonna do?
Do you remember the formula for area ratio?
Do you remember the dreams of your childhood?
Who threw those dreams in a ditch?
Who was it!? You know who it was!
When are you going to grow up!?
What is a grown-up anyway?
Who has the answers?
What're you gonna do? I don't care anymore!
