[Verse 1] You walk in slow And my whole chest changes One little glance And I forget my name, babe Your mouth curves up Like you know my secret I try to stay cool But I never beat it [Pre-Chorus] 'Cause the room goes soft And my pulse runs quick One smile from you And I fall right in it I don't need much Just that look today You pull me close Without moving away [Chorus] When you smile at me I come undone (I come undone) When you smile at me Baby, that's the one (that's the one) When you smile at me My whole world leans in When you smile at me I believe again (I believe again) [Verse 2] Your laugh hits low In that sweet small way Like a sunbeam caught On a dinner plate I hold your hand Like it's made of glass 'Cause every good thing Seems too good to last [Pre-Chorus] But you look at me Like I'm safe with you Like all my noise Turns into truth So I breathe you in And let it stay One smile from you Can save my day [Chorus] When you smile at me I come undone (I come undone) When you smile at me Baby, that's the one (that's the one) When you smile at me My whole world leans in When you smile at me I believe again (I believe again) [Bridge] Say my name slow Let it hang there Put that sweet light Right through the air If time runs out If the night falls hard Keep that smile on me Like a lucky card [Final Chorus] When you smile at me I come undone (I come undone) When you smile at me Baby, that's the one (that's the one) When you smile at me My whole world leans in When you smile at me I believe again (I believe again) When you smile at me I know I'm home When you smile at me I never feel alone
