Someone has told the speaker they were "just wondering" whether they like them, and the speaker can't stop turning that phrase over. It's a poem about the nervous, hopeful stage of a crush, when every casual remark might be a signal or might be nothing at all.
The speaker opens with a blunt "I like you," then spends the rest of the poem circling around what the other person actually meant. The repeated "just wondering" and "just asking" start to sound less like reassurance and more like a worry being picked at. The apology for being awkward, followed by the quick "Good awkward" and "Of course," suggests the speaker is trying to sound relaxed while feeling anything but.
The mood is playful, anxious and a little giddy. The short lines and rhymes, like "flirtatious" and "outrageous" or "confess" and "obsess," give it a breathless, teasing rhythm. It ends on a question, leaving the speaker still waiting for an answer.
