The speaker looks back on a close bond with someone they call "Tol," a person who seemed enormous to them. The word "smol," a playful, childlike way of saying "small," sets a tender tone from the start. Together they were "giants" in a tiny world, as if their closeness made everything else shrink. The speaker felt small next to this person, yet also felt that they were looking up to someone who mattered a great deal.
The middle of the poem admits that affection did not come easily. Still, the difficulty "never stopped" the other person from trying, which the speaker clearly values. The image of "invisible strings" around their hearts suggests a connection that formed slowly and quietly, without either of them forcing it. The short last line, "So we waited," feels calm and accepting. The mood is warm, gentle, and a little wistful, a quiet celebration of patience and of love that took its time.
