Hojo, a motorcycle courier, takes a delivery order to an apartment and meets Aranami, a popular novelist. The encounter takes a turn when Hojo accidentally witnesses Aranami with his male partner, and realizes Aranami is gay. Certain they have no reason to meet again, Hojo is surprised when he receives another mail order from Aranami a few days later. The story unfolds as a slow-burn boys' love romance driven by quiet revelation and the collision of two very different lives—a grounded working-class courier and a successful but private author. Set in a contemporary urban environment, the narrative focuses on subtle emotional beats, gradual exploration of identity, and the ways their professional and personal worlds intersect. Hojo is earnest and observant; Aranami is reclusive and guarded. Their relationship develops through repeated encounters, unspoken tensions, and small gestures, avoiding loud melodrama in favor of character-driven intimacy. The manga emphasizes internal discovery, the melting of barriers between the two men, and the tender process of mutual understanding.
