[Verse 1]
Have you ever had one of those dreams
About a random other person
Where you wake up with a crush and you're like, "Fuck" (Fuck)
And you open your eyes, you look to your right
And your brain is kinda hurting
'Cause you wish that was the person you just fucked (Fuck)

[Pre-Chorus]
And now I feel guilty
I don't know what to do
We've been kissing for two years in my room, but

[Chorus]
Truth is I been sitting, thinking 'bout somebody else
I been out here crossing fingers hoping you could never tell
I know that you'll be mad because it's someone we both knew
I'm a liar, I'm a cheater, I'm in love with the old you

[Verse 2]
I've been thinking 'bout learnin 'bout physics
To try and travel back in time
To when the feelings and the sex was fucking wild
I don't wanna lie when I'm with you
Don't wanna offend you, I miss you
But I'm touching myself to the thought of the old you
[Chorus]
Truth is I been sitting, thinking 'bout somebody else
I been out here crossing fingers hoping you could never tell
I know that you'll be mad because it's someone we both knew
I'm a liar, I'm a cheater, I'm in love with the old you

[Bridge]
I'm in love with the old you (With the old you, old you, old you)
I'm in love with the old you

[Chorus]
Truth is I been sitting, thinking 'bout somebody else
I been out here crossing fingers hoping you could never tell
I know that you'll be mad because it's someone we both knew
I'm a liar, I'm a cheater, I'm in love with the old you

[Outro]
I'm in love, I'm in love with the old you
I'm in love, I'm in love, I'm in love
