It was unpredictable
Right down to the chemical
Caught me off guard
Never saw you coming, no
Want you, but I shouldn't, though
Takes a lot of self-control
Not to disclose
All the times I thought about

You could lead to something
If we keep it up, no doubt, it could lead to something
You wanna let you know something

The thing about me
If I'm going in, then I'm going in deep
I could give you love that you wouldn't believe
Only want your heart if you're playing for keeps
The thing about me
Once I'm all in, I ain't ever gon' leave
I'll be by your side, so you're never lonely
Only want your heart if you're playing for keeps

I don't wanna complicate
I can't help but hesitate
Need to know if, if you're on a different page
Kinda wanna cross the line
Wanna know if you'll be mine, mine

You... Could lead to something
If we keep it up, no doubt, it could lead to something
You... Wanna let you know something

The thing about me
If I'm going in, then I'm going in deep
I could give you love that you wouldn't believe
Only want your heart if you're playing for keeps
(Playing for, playing for keeps)
The thing about me
Once I'm all in, I ain't ever gon' leave
I'll be by your side, so you're never lonely
Only want your heart if you're playing for keeps

Oh-oh-oh-oh-oh, playing for, playing for keeps
Oh-oh-oh-oh-oh, playing for keeps
Oh-oh-oh-oh-oh, only want your heart
Oh-oh-oh-oh-oh, the thing about, thing about me
If I'm going in, then I'm going in deep
I could give you love that you wouldn't believe
Only want your heart if you're playing for keeps
