英文版：
I miss you so much, it's killing me
But you're out there, doing what you're doing
I can't deny, it's driving me crazy
When you're around the clouds disappear
And I, I don't even care about anything else
When you're near me, my heart melts like ice cream
When you look at me that certain way, that certain way
It's a shame, I know it's not okay
But I want you back, I want you back
In my life again, again
Just give me a chance to make it right
And I'll sing the same song, sing the same song
I want you back, I want you back
In my life forever, forever
I'll do anything to make it real
If you take me back, take me back
中文版：
我如此思念你，思念得快要發狂
但你在那裡做著自己的事
我無法抗拒，它讓我瘋狂
當你靠近我，雲朵就消失無蹤
我，我無所謂其他了
當你靠近我，我心中的愛情就像冰淇淋般融化
當你以那特別的方式看著我，那特別的方式
可惜，我知道這並不適合我
但我希望你能回來，希望你能再次回到我的生命中
只要給我一個機會讓我修正這一切
而我將唱著同一首歌，唱著同一首歌
我希望你能回來，希望你能永遠回到我的生命中
我將做任何事情使這成為真實的
如果你帶回了我，帶回了我
希望這些歌詞對您有所幫助！
