Sabrina, a white-collar worker, transmigrated into a male-oriented novel as Princess Serena, the villainess destined to die a tragic death. To survive, she fiercely protected her husband Axel and made a divorce deal with him, all while starting a cosmetics business. Using her modern mindset and foreknowledge, she faked illness to extort money, outmaneuvered court plots, saved a prince, and averted a birthday banquet crisis, secretly gathering evidence of the crimes committed by the villainous elder princess. In the end, the villain fell. But Axel, his ears red, confessed that he didn't want to part ways. Sabrina laid out three conditions. No taking concubines, no interference in her shop, and that he must back her up whenever she got into a fight. Axel agreed to everything, and the two ended up happily together.
