女生版：
I'm so confused
Been sitting here thinking
About you and me
What we could have been
Every time I think
About what could have been
My heart aches
Cause I'm lovesick
男生版：
Girl I'm so confused
Been sitting here wondering
If you're feeling me
Or if you're lonely
Every time I think
About what could have been
My heart aches
Cause I'm lovesick
I'm lovesick
And I don't know what to do
I'm so unsure
But I'll learn to trust you
Oh baby
女生版結尾部分有一句“I'm lovesick again”，表示相思病再次來襲。男生版則是“I'm lovesick and I need your love”，表示相思病已經讓他無法自拔，只能尋求女生的愛情。
