Cover
A New PeriWinkle Title Built on Contract Marriage and an Obsessive Duke
계약 결혼이라면서요, 공작님 launched exclusively on Naver Series under PeriWinkle in early August 2026. It received a daily serialization slot and is currently ongoing.
The official synopsis describes the female lead, a former corporate lawyer, waking up in the body of a debt-ridden extra. While simply trying to survive, she accidentally takes over the business of Kailon, the empire's ultimate obsessive male lead. Instead of punishment, he offers her a three-year marriage contract as duchess. When the contract expires and she presents divorce papers, he tears them up and refuses to let her go.
An Imperial Setting with a Highly Obsessive Husband
The protagonist tries to treat the marriage as a pure business arrangement. However, Kailon, who was supposed to merely monitor her, grows increasingly possessive. He buys every variety of flower she likes from across the continent and acquires entire trading companies that catch her interest.
The official synopsis emphasizes that what began as a marriage of convenience is transforming into something far more intense.
The Cover Features a Pink-Haired Heroine and a Black-Haired Duke
The official cover illustration shows the two leads on a beautiful balcony. On the left sits a long pink-haired woman in a mint-green frilled dress, holding a book. On the right stands a black-haired man with golden eyes, dressed in a formal black-and-green suit, gazing at her with a soft yet intense expression. The background is filled with flowers and greenery.
The composition highlights the romantic yet tension-filled atmosphere between the clever contract wife and the obsessive duke.
Contract Relationship That Turns into Obsession
The story centers on the dynamic between a genius wife skilled in law and ledgers and a husband madly in love with her. Contract marriage, transmigration, an obsessive male lead, and a "legitimate" romance form the core appeal of the novel.
Why This Matters
1) Strong contract marriage + transmigration premise
A modern corporate lawyer reborn into a debt-ridden extra who ends up in a contract marriage with an obsessive duke creates immediate conflict and interest.
2) Obsessive ML who refuses divorce
Kailon does not simply reject the divorce — he becomes extremely possessive, a classic trait of the genre.
3) Competent and clever female lead
The heroine is not passive. Her expertise in law and business allows her to navigate and even exploit the imperial system.
4) Visually striking official cover
The cover immediately establishes an elegant romantic atmosphere and strong character contrast.
