[Verse 1]
Build a wall of books between us in our bed
Repeat, repeat the words that I know we've both said
Relax into the need, we get so comfortable
Remember when I was so strange and likable?

[Hook]
I just want back in your head
I just want back in your head
I'm not unfaithful but I'll stray
When I get a little scared
When I get a little scared
When I get a little

[Verse 2]
When I jerk away from holding hands with you
I know these habits hurt important parts of you
Remember when I was sweet and unexplainable?
Nothing like this person, unlovable

[Hook]
I just want back in your head
I just want back in your head
I'm not unfaithful but I'll stray
When I get a little scared
When I get a little scared
When I get a little
[Bridge]
Run, run, run, run
Run, run, run, run

[Hook]
I just want back in your head
I just want back in your head
I'm not unfaithful but I'll stray
I'm not unfaithful but I'll stray
I'm not unfaithful but I'll stray
I'm not unfaithful but I'll stray
