歌詞：
First sight, you caught my eye
第一次看到你，我被你吸引
Didn't even talk to you yet
甚至還沒和你說過話
Just the way you walked, just the way you smiled
只是你走路的樣子，只是你微笑的樣子
I knew it was something real
我就知道這是一份真實的感情
I can't explain it, it's just a feeling
我無法解釋，這只是一種感覺
Like I knew we were supposed to be
就像我明白我們應該在一起一樣
Even though we don't know each other
即使我們還不熟悉
Chorus:
First sight, I knew it was you
第一眼看到你，我就知道是你
No matter what, I'm not letting go
無論如何，我都不會放你走
Even if we don't say a word to each other
即使我們一句話都不說
I can feel it, it's something real
我也能感覺到，這是一份真實的感情
Verse 2:
It's not like I'm obsessed or anything
我並不是痴迷或者怎樣的
But every time I think about you
但每次我想到你
My heart skips a beat, I can't explain it
