[Verse 1]
I guess I was wishing on falling stars
'Cause all my come true wishes seemed to fall apart
I'd always end up with a restless heart

[Pre-Chorus]
Until I met you, you, you
I never knew, knew, knew
That I was so lonely
But now I'm so happy
I can't explain it
When people ask me

[Chorus]
How do you know this is love?
How do you know this is true?
How can you even understand?
You're way to young to have a clue
Maybe you're just infatuated
Pretty sure you're just confused
How do you know if it's really love?
You just do
I don't know how, I just do

[Verse 2]
Just like I know the sun will rise today
And I don't have to question every single breath I take
Now I see the world a whole new way

[Pre-Chorus]
'Cause I met you, you, you
I never knew, knew, knew
That all of the lonely will turn into happy
That's how I explain it
Whenever they ask me

[Chorus]
How do you know this is love?
How do you know this is true?
How can you even understand?
You're way to young to have a clue
Maybe you're just infatuated
Pretty sure you're just confused
How do you know if it's really love?
You just do
Don't know how

[Bridge]
I just feel it in my heart
Like a cool summer breeze
Now I hear it in the wind
Like a song that angels sing
See it in your eyes
Every time you look at me
You don't care and I don't care what they believe
When they say

[Chorus]
How do you know this is love?
How do you know this is true?
How can you even understand?
You're way to young to have a clue
Maybe you're just infatuated
Pretty sure you're just confused
How do you know if it's really love?
You just do
Don't know how, I just do
Don't know how, I just do
