One is you make me happy

Two is you set me free

From all the things that held me

Back from just being me

Thank you for all the sweetness

Now I can finally breathe

Now I can finally breathe

But baby, don't you see?

I still get frustrated, I can't lie

When you keep on doing things I don't like

And I hate your friends

And I hate your moods

And I shouldn't love you

But I got 21 reasons why I do-do-do-do

Do-do-do-do-do, do-do-do-do

I got 21 reasons why I do-do-do-do

Do-do-do-do-do, do-do-do-do

I got 21 reasons why I do

Three is the way you hold me

That's what I waited for

Five shots we're getting naughty

Movin' around the floor

You took away the lonely and I let you come for me

Loving the company

But baby, don't you see?

I still get frustrated, I can't lie

When you keep on doing things I don't like

And I hate your friends (your friends)

And I hate your moods (moods)

And I shouldn't love you

But I got 21 reasons why I do-do-do-do

Do-do-do-do-do, do-do-do-do

I got 21 reasons why I do-do-do-do

Do-do-do-do-do, do-do-do-do

I got 21 reasons why I do

My friends say you ain't good enough

And maybe I should give you up (give you up)

But I got my reasons and here comes another one

Here comes another one

One, two, three, four, five, six, seven, eight, nine, ten

Keep on countin'

I shouldn't love you

But I got 21 reasons why I do-do-do-do

Do-do-do-do-do, do-do-do-do

I got 21 reasons why I do-do-do-do

Do-do-do-do-do, do-do-do-do

I got 21 reasons why I do

One, two, three, four, five, six, seven, eight, nine, ten

Keep on countin'

I shouldn't love you

But I got 21 reasons why I do-do-do-do

Do-do-do-do-do, do-do-do-do

I got 21 reasons why I do
