[Romanized:]

Nande anata wa, nande utsumuku
Nande bokura wa, tell me aishitemo
Deguchi nai tonight kono mama ja tsurai
Soba ni zutto butterfly, oh I'll be crazy

You, dareka hoka ni suki na hito ga iru no nara
You, sou janakute boku no kimochi shitte hoshii

Kotae ga kowai no wa anata wo ai shisugite
Daiji na kotoba saemo to you ienai ienai ienai

Motto shinjite, motto mitsumete
Motto bokura wa, I know kanjiteta
Todokanai yo cry, mou iki mo dekinai
Miushinatta butterfly, oh I'll be crazy

Love, mayoi konda michi no hatede tachi tomaru
Baby, dou sureba ii tobira no kage wo sagashiteru yo

Tsumetai yoru no naka anata wo dakishimetemo
Kokoro no oku no kimochi I can't mienai mienai mienai

Nande anata wa, nande utsumuku
Nande bokura wa, tell me aishitemo
Deguchi nai tonight kono mama ja tsurai
Soba ni zutto butterfly, oh I'll be crazy

Kizutsuitedemo tsuetai yo
Koukai nado shitakunai kara
Kono omoi dake tsutetai yo I need you girl

Motto shinjite, motto mitsumete
Motto bokura wa, I know kanjiteta
Todoku made to shine believe akiramenai
Dakara kitto butterfly oh I'll be crazy

[Japanese:]

何であなたは 何でうつむく
何で僕らは Tell me 愛しても
出口ないtonight このままじゃつらい
そばにずっとbutterfly oh I'll be crazy

You 誰か他に好きな人がいるのなら
You そうじゃなくて 僕の気持ち知って欲しい

答えが怖いのはあなたを愛しすぎて
大事な言葉さえも to you 言えない言えない言えない

もっと信じて もっと見つめて
もっと僕らは I know 感じてた
届かないよcry もう息も出来ない
見失ったbutterfly oh I'll be crazy

Love 迷い込んだ道の果てで立ち止まる
Baby どうすればいい 扉の翳を探してるよ

冷たい夜の中 あなたを抱きしえても
心の奥の気持ち I can't 見えない見えない見えない

何であなたは 何でうつむく
何で僕らは Tell me 愛しても
出口ないtonight このままじゃつらい
そばにずっとbutterfly oh I'll be crazy

傷付いたでも伝えたいよ
後悔などしくないから
この想いだけ伝えたいよI need you girl

もっと信じて もっと見つめて
もっと僕らは I know 感じてた
届くまでto shine believe諦めない
だからきっとbutterfly oh I'll be crazy

[English translation:]

Why you, why do you hang your head in shame
Why we tell me it's ok to love
There's no exit tonight, it's painful like this,
Next to you forever, butterfly, oh I'll be crazy

You, if you have someone else who you like
You, if not, I want you to know my feelings

The answer is scary, I love you too much
The important words, I can't say them clearly to you, I can't say, I can't say

Believe more, gaze more
I know, we felt it more
I can't reach you, cry, I can't even breathe
The butterfly I didn't lose, oh I'll be crazy

Love, the street crowded with hesitation, until the end remains standing
Baby, what should I do, I'm searching for the other side of the door

In this cold night, I can hold you
I can't see the feelings inside of your heart, I can't see, I can't see

Why you, why do you hang your head in shame
Why we tell me it's ok to love
There's no exit tonight, it's painful like this,
Next to you forever, butterfly, oh I'll be crazy

Even though I might be wounded, I want to convey this
Because I don't want to do anything regretful or something like that
I want to send only this feeling, I need you girl

Why you, why do you hang your head in shame
Why we tell me it's ok to love
Until I reach it, to shine, believe, I won't give up
So, for sure butterfly, oh I'll be crazy
