Fionna was gazing out at the star on the balcony

We were both knights when I first saw you

I close my eyes

And the flashback starts

I'm standing there

On a balcony with the tree house air

See the kingdoms

See the party, the ball gowns

I see you make your way through the crowd

You say ''hello'', little did I know

That you were Finn, you were raised by dogs

And my sister, Cake said stay away from Fionna

And I was crying in my bunny hat

Begging you please don't go, and I said

''Finn please take me somewhere we can be alone

I'll be waiting all there's left to do is run

You'll be the hero and I'll be the heroine

It's a love story baby just say yes"

Finn and Fionna snuck out of their treehouses and saw each other at the forest

So I sneak out to the forest to see you

We keep quiet 'cause we're dead if they knew

So close your eyes

Escape this tree house for a little while

'Cause you were Finn, I was just a vicious tomboy

And my sister Cake said stay away from Fionna

But you were everything to me

I was begging you please don't go and I said

''Finn please take me somewhere we can be alone

I'll be in the forest all there's left to do is run

You'll be the hero and I'll be the heroine

It's a love story baby just say yes''

''Finn please save me, they're trying to tell me how to feel

This love is difficult, but it's real

No need to worry, we'll make it out of this mess

It's a love story baby just say yes''

Oh oh oh oh

But as of then, Finn had stopped showing up at the forest.

I got tired of waiting

Wondering if that bear hat was ever coming around

My faith in you was fading

When I met you in the forest, and I said

''Finn please save me I've been feeling so alone

I keep waiting for you but you never come

Is this in my head? I don't know what to think"

But as the fourth night, Finn had shown up again. He knelt on one knee on the grass.

Finn knelt to the ground and pulled out a ring and said

''Marry me Fionna, you'll never have to be alone

I love you whether if you were raised by cats

I talked to your sister, go pick out a white dress

It's a love story baby just say... yes"

Oh, oh, oh, oh

'Cause we were both knights when I first saw you.

Fionna picked out a lovely white dress, and Fionna and Finn saw each other again at the end of the aisle in the forest and shared their love with a ever lasting kiss.
