Baby, the worst jail is
Waking up alone in a world where you’re not mine
In a room painted off white
Running out in the daylight, tryna get back to you
Considering what a jail is — here, Frank is saying that the worse form of jail is waking up and she is no longer with him. This could imply that he loves her so much that he can’t go anywhere or do anything without her with him.
