The speaker is trying to work out why they feel so drawn to another person. They go hunting for one answer: maybe it's the glowing eyes, maybe the voice when the person talks about something they love, maybe the clumsy way they multi-task. Each guess is a small, affectionate detail, but none of them turns out to be the "anchor" the speaker is looking for.
The poem's turn comes near the end. After searching "countless times," the speaker realises there is no single hidden cause. The person, awkwardness and all, is the anchor. The speaker is pulled in by all of them, not by one feature.
The mood is gentle, curious and tender. The opening feels puzzled and a little restless, with its repeated "I can't," but it settles into quiet certainty. The speaker doesn't just love the person's best qualities; they love the awkward ones too, and that makes the feeling sound honest.
