O month when they who love must love and wed.

The line apostrophizes a particular month as a culturally sanctioned season for romance’s culmination—courtship turning into marriage. Its compressed phrasing (“must love and wed”) suggests both urgency and social expectation: love is not only felt but enacted publicly through wedlock. The tone is celebratory yet faintly ironic in its emphasis on necessity, hinting at how seasonal rituals (springtime, June weddings, etc.) can pressure private feeling into conventional forms. As a lyric fragment, it also works as a miniature calendar-myth, turning time itself into an agent that summons lovers toward commitment.
