A speaker is quietly in love and can't yet say so. The person they care about is out of sight but never out of mind, filling their thoughts and even their prayers. They want to confess everything, but the timing feels wrong. The image of the sun not yet risen and the rooster not yet crowing makes the feeling seem like an early morning, full of promise but not quite begun.
So the speaker waits. The "XO" (hugs and kisses) sits alone between stanzas like a small sign-off the speaker can't fully deliver. The offer to "bring my gum" is a small, sweet, slightly awkward detail, suggesting hopeful nerves about a first close moment.
The final stanza turns into a rush of "What if" questions: What if this is love? What if she feels the same? What if it lasts? The mood is shy, tender and hopeful, with the excitement of someone daring to imagine happiness.
