《西野if》的歌詞如下：
西野的淚光 閃爍在唇上
靜靜嘗著 背叛的傷
你是個迷 我是個謊
相愛的形狀 變了形狀
回憶不腐 像死去的花
若沒在美夢裏溺死 就別醒來
If I fall into the abyss of love
Should I still believe in tomorrow?
My eyes can't bear the tears anymore
And my heart is shattered into pieces
I want to cry for you, forever and ever
But you won't feel my pain, will you?
淚流成河 我用愛洗澡
每個靈魂 都殘破不堪
越陷越深 越掙扎越亂
我的心在流浪 而你在哪端?
If I fall into the abyss of love
Should I still believe in tomorrow?
My eyes can't bear the tears anymore
And my heart is shattered into pieces
I want to cry for you, forever and ever
But you won't hear my pain, will you?
你的微笑 我的煎熬
像場荒誕的鬧劇 誰會笑?
愛恨都潦草 眼淚別潦草
別讓遺憾 耗盡我們的好
If I fall into the abyss of love
Should I still believe in tomorrow?
If I fall into the abyss of love again
Will I still believe it's not forever?
Oh baby, I want to go back
To the moment when we first fell in love...
But it's too late, everything's changed...
