Lyrics:

Found your love letters to her
I'm tryna be cool, but it really fucking hurts
I'll just do what I do, silently torturin' myself
Was her ocean deeper than mine?
Did you sink into her, fall in love at first sight?
I know we're good, but I'm constantly comparing myself
It's irrational and impossible
'Cause I know you had a life before me
But I'm jealous, obsessive
And I wanna burn all your history, burn your history
Can I have your heart in a plastic box? (Oh)
Never used, fully clean, untouched (oh, ooh)
Like I'm the only one you've ever loved
Can I have your heart in a plastic box?
Can I have your heart in a plastic box? (Never used)
Never used, fully clean, untouched (oh, oh)
Like I'm the only one you've ever loved
Can I have your heart in a plastic box? (Yeah)
Are you sure you feel the same way? (Feel the same way?)
'Cause it took me months, it only took her a day (oh)
To make you jump in
I read it in your handwritin'
It's irrational and impossible
'Cause I know you had a life before me
But I'm jealous of your exes
And I wanna burn all your history (wanna burn all your history, ah)
Can I have your heart in a plastic box? (Oh, whoa-whoa)
Never used, fully clean, untouched (oh, yeah)
Like I'm the only one you've ever loved
Can I have your heart in a plastic box? (Can I have your heart?)
Can I have your heart in a plastic box? (Oh, never used)
Never used, fully clean, untouched (only one you loved)
Like I'm the only one you've ever loved
Can I have your heart in a plastic box?
Can I have your heart?
Never used, untouched
(Mm, oh) only one you loved
Can I have your heart? (Hey, yeah, yeah, yeah)
(Oh, can I have your heart?)
Can I have your heart in a plastic box? (Never used, untouched)
Never used, fully clean, untouched (oh, ooh, only one you loved)
Like I'm the only one you've ever loved (you've ever loved)
Can I have your heart in a plastic box? (Yeah)
Can I have your heart in a plastic box?
(Can I? Can I? Never used, untouched)
Never used, fully clean, untouched (so untouched)
Like I'm the only one you've ever loved (you've ever loved)
Can I have your heart in a plastic box?
