[Japanese:]

寂しさは凶器だ
人を傷つけてしまう
それに気付けなくなる
愛しさは病気だ
胸が苦しくなるよ
治し方はないんだ

この日々は奇跡だ
でも何かが足りない
埋まらない　空欄
君は　不思議だ
その存在が僕を
強くも　弱くもする

僕らはどうかな　上手いこと
「人間」をできてるかな
どうかな　どうかな
深まりながら　まるつけ

優しさは積み木だ
積み上げれば高くなる
だけれど　脆くもなる
正しさは正義だ
だけど人は踏み外す
それを救うのは何？

僕らはどうかな　ふたりで
「人生」をやれるかな
どうかな　どうかな
願いを込め　まるつけ

「人生」は天気だ
晴れたり降られたりする
どちらも起こりうる
どうかな　傘なら
僕が持っておくから
ふたりでひとつになろう？

[Romanized:]

Samishisa wa kyouki da
Hito wo kizutsukete shimau
Sore ni kizukenakunaru
Itoshisa wa byouki da
Mune ga kurushiku naru yo
Naoshikata wa nain da

Kono hibi wa kiseki da
Demo nanika ga tarinai
Umaranai kuuran
Kimi wa fushigi da
Sono sonzai ga boku wo
Tsuyoku mo yowaku mo suru

Bokura wa dou ka na umai koto
"Ningen" wo dekiteru ka na
Dou ka na dou ka na
Sagurinagara marutsuke

Yasashisa wa tsumiki da
Tsumiagereba takaku naru
Dakeredo moroku mo naru
Tadashisa wa seigi da
Dakedo hito wa fumihazusu
Sore wo sukuru no wa nani?

Bokura wa dou ka na umai koto
“Renai” wo dekiteru ka na
Dou ka na dou ka na
Kotae mo naku marutsuke
Bokura wa dou ka na futari de
"Jinsei" wo yareru ka na
Dou ka na dou ka na
Negai wo kome marutsuke

"Jinsei" wa tenki da
Haretari furaretari suru
Dochira mo okoriuru
Dou ka na kasa nara
Boku ga motte oku kara
Futari de hitotsu ni narou?

[English translation:]

The feeling of loneliness is insane
It hurts people's feelings
And it's difficult to realize it
Love is an illness
My chest began to ache
There's no way to treat it

These days are like a miracle
But nothing is enough
To fill up the emptiness

You are wonderful
You make me feel
Both strong and weak
What about us?
I wonder if we can live as good "people"
I wonder, I wonder
I'm checking the answers while searching

Kindness is like building blocks
It can pile up high
But it will become unstable
Justice is right
But people still don't follow that path
What could be there to save them?

What about us?
I wonder if we can live our "lives" together
I wonder, I wonder
I'm checking the answers with hope

"Life" is like weather
Cloudless, raining, snowing
Either can happen
What about an umbrella?
I keep holding one
So let's get under it together
