《My Fault》的詞曲是由Lindstrøm和Kato共同完成，歌詞如下：
I know I hurt you, I know I let you down
我知道我傷了你，我知道我讓你失望
I never meant for any of this to happen
我始終沒有意圖讓任何事情發生
I guess I never really knew you
我想我始終不了解你
All the things that I should have said
所有我應該說的話
All the things that I should have done
所有我應該做的事
I don't know what to say or do now
我不知道現在該說什麼或做什麼
Chorus:
My fault, I know it was wrong
是我的錯，我知道是我不對
But if you give me a chance to explain
但如果你給我一個機會讓我解釋
I would never intentionally hurt you
我永遠不會故意傷害你
My fault, I know it was me
是我的錯，我知道是我自己的問題
But if you give me a chance to prove
但如果你給我一個機會讓我證明
That I'm a changed man who won't hurt you again
我是個已經改過自新的人，不再傷害你
Time for you to put your trust in me again
你應該再信任我一回的時候來了
The distance may have separated us now
時間可能將我們分隔開來
But if you let me back into your life again
但如果你讓我再回到你的生活中去
I will make it right
我會讓一切回到正軌上
I'll do better by you this time, my love will be stronger (my love will be stronger)
