I Became the Prince’s Wicked Wife is a 45-episode bilingual historical fantasy rom-com. Modern-day Selena wakes up in a medieval fantasy world as the notorious wife of Prince Arthur, caught mid-way through whipping him. Realizing she has transmigrated into a novel where her character steals a border defense map for her lover, Prince Leon, and is ultimately executed, she immediately stops the abuse, apologizes, and returns the map.
To prove her innocence, Selena makes a deal with Arthur to help expose Leon's plot. She faces interrogation, house arrest, and blackmail from her own family, but through her sharp wits and modern mindset, she unearths a massive corruption scheme involving military supplies, survives an ambush, and helps foil a palace coup staged by the king's ruthless brother, Roland. Along the way, she confesses the truth of her transmigration to Arthur. He chooses to trust her—not just as the mother of his unborn child, but as his equal partner. After defeating the rebels and saving the king, Arthur ascends the throne, re-proposes to her with vows of their own making, and crowns her as Queen. Together, they build a new life and a better kingdom, proving that she has rewritten her tragic ending into a happy one.
