Kanae Yano, a 28-year-old single woman with no romantic prospects, is suddenly transported to a fantasy world. There, she meets Rita Scryne, a duke’s daughter who looks exactly like her, along with Rita’s father, Zack. Desperate to protect his daughter, Zack asks Kanae to impersonate Rita and enter an arranged marriage with the infamous King Eugene Astaroth, feared across the land as the “Merciless Wolf.” When Kanae learns that the summoning magic cannot return her to her original world, she has no option but to agree. But everything changes when she finally meets the king and uncovers a stunning truth—King Eugene is actually her long-lost first love.
