Su Yu, a PhD in engineering, transmigrates into the body of a hostage prince from an enemy kingdom and is forced to disguise himself as a woman to marry the war goddess princess, Tang Yao. To save his life, he develops high-tech gadgets for cross-dressing, but Tang Yao catches him in the act and starts a little taming game. When he hides gunpowder in magnetic fake breasts, she laughs; when he uses a hoop skirt as a shield against blades, she films him; when he says for the seventh time, “This time I’m definitely changing back into men’s clothes,” she tears open her wedding gown to reveal armor: “My dear consort, my wedding gift to you is the history of your cross-dressing.”
