[Verse 1: Dean Lewis]
I'm so scared of falling
I was in and out, up and down, too afraid to be open
I found myself in you and it made me feel so scared
'Cause, when I am open
All my past and all my pain floats up to the surface
You can even cut me down with a smile, it hurts so bad

[Pre-Chorus: Dean Lewis]
So, I leave when it gets too good, yeah-yeah
I leave when it gets too good
But

[Chorus: Dean Lewis, Julia Michaels, Dean Lewis & Julia Michaels]
In a perfect world, I am here with you
And I kiss you slow in a dim-lit room
When you ask me if I love you, I say, "I do"
I'm not running from my problems, and I'm not running from you
And we're so damn happy, and I'm not confused
I'm not looking for an escape all 'cause I'm scared I might lose you
Ooh, in a perfect world

[Verse 2: Julia Michaels]
Yeah, at least you're self-aware, I'll give you some credit
But walking out on something perfect's really stupid, yeah
Baby, I said it
You're so scared of regretting something before you can even regret it
And we could be great, and it would be great if you'd let it, uh
[Pre-Chorus: Julia Michaels, Dean Lewis, Dean Lewis & Julia Michaels]
But you leave when it gets too good, yeah-yeah
You (I) leave when it gets too good
But

[Chorus: Dean Lewis & Julia Michaels, Julia Michaels]
In a perfect world, I am here with you
And I kiss you slow in a dim-lit room
When you ask me if I love you, I say, "I do"
I'm not running from my problems, and I'm not running from you
And we're so damn happy, and I'm not confused
I'm not looking for an escape all 'cause I'm scared I might lose you
Ooh, in a perfect world

[Bridge: Dean Lewis & Julia Michaels, Julia Michaels, Dean Lewis]
I leave when it gets too good (When it gets too good, you always)
Leave, leave, when it gets too good
Oh, but

[Outro: Dean Lewis & Julia Michaels, Julia Michaels]
In a perfect world, there's just us two
And I let myself get lost in you
When you ask me if I love you, I say, "I do"
I'm not running from my problems, and I'm not running from you
