Act I: In front of Castle Bunthorne, a group of "lovesick maidens" are all in love with the aesthetic poet Bunthorne ("Twenty lovesick maidens we"). Lady Jane, the oldest and plainest of the ladies, informs them that Bunthorne, far from returning their affections, has his heart set on the simple milkmaid Patience. Patience appears and confesses that she has never loved anyone; she is thankful that love has not turned her miserable as it has them ("I cannot tell what this love may be"). Soon, the ladies' old sweethearts, the Dragoon Guards, appear ("The soldiers of our Queen"), led by Colonel Calverley ("If you Want a Receipt for that Popular Mystery"), Major Murgatroyd, and the droopy but immensely rich Lieutenant the Duke of Dunstable. They arrive ready to propose, only to discover their intendeds fawning over Bunthorne, who is in the throes of poetical composition, pretending to ignore the attention of the ladies thronging around him ("In a doleful train"). Bunthorne reads his poem and departs, while the officers are coldly rebuffed and mocked by the aesthetic ladies, who turn their noses up at the sight of their red and yellow uniforms. The Dragoons, reeling from the insult, depart ("When I first put this uniform on"). Bunthorne, left alone, confesses that his aestheticism is a sham, and mocks the movement's pretensions ("If you're anxious for to shine"). Soon, he reveals to Patience that, like her, he does not really like poetry, but she tells him that she could not love him. Later, Lady Angela, one of Bunthorne's admirers, explores with Patience the latter's childhood crush ("Long years ago"). Lady Angela rhapsodises upon love as the one truly unselfish pursuit in the world. Impressed by this eloquence, Patience promises to fall in love at the earliest opportunity. That opportunity is provided by the arrival of Archibald Grosvenor, another aesthetic poet who turns out to be Patience's childhood love. He has grown up to be the infallible, widely loved poet known as "Archibald the All-Right" ("Prithee, pretty maiden"). The two declare themselves in love but are brought up short by the realisation that as Grosvenor is a perfect being, for Patience to love him would be a selfish act, and therefore not true love; thus, they must part. Bunthorne, heartbroken by Patience's rejection, has chosen to raffle himself off among his lady followers ("Let the merry cymbals sound"), the proceeds going to charity. The Dragoons interrupt the proceedings, and, led by the Duke, attempt to reason with the ladies ("Your maiden hearts, ah, do not steel"), but the ladies are too busy clamouring for tickets to the raffle to listen ("Come walk up"). Just as Bunthorne is handing the bag to the unattractive Jane, ready for the worst, Patience interrupts the proceedings and proposes to unselfishly sacrifice herself by loving the poet ("True Love must single-hearted be"). A delighted Bunthorne accepts immediately, and his followers, their idol lost, return to the Dragoons to whom they are engaged ("I hear the soft note of the echoing voice"). All seems resolved until Grosvenor enters and the ladies, finding him poetic, aesthetic, and far more attractive than Bunthorne, become his partisans instead ("Oh, list while we a love confess"), much to the dismay of the Dragoons, Patience, Bunthorne and especially Grosvenor himself.
