My Male Lead is the Dark-Haired Northern Duke

[The Male Lead who is abandoned by the female lead is pitiful—I Raised Him into a Perfect Northern Dark-Haired Duke, but Now He’s Obsessed with Me!] “Once upon a time, there lived a Northern Black-Haired Duke. The Northern Black-Haired Duke always took baths with cold water, and no matter how cold it got, he never wore outer clothes. During tea time, he only drank cold water.” “Minelli, what is the Northern Black-Haired Duke?” “The Northern Black-Haired Duke is…” What else could it be? It’s what you’re going to grow up to be. * I thought I had died in a car accident, but instead, I was reborn as the playmate of the Northern Duke’s heir. But this heir, poor thing, is sickly, always in ill health, and destined to have the princess taken away by another man. ‘In that case, I’ll help him become the perfect Northern Black-Haired Duke and achieve love!’ That was my plan, but… Why is our Setsu so cute and sweet? Can I really succeed? “I’m only kind to you.” **Original Novel:** [KakaoPage](https://page.kakao.com/content/56749512), [Naver Series](https://series.naver.com/novel/detail.series?productNo=8709079) **Original Webtoon:** [Naver Series](https://series.naver.com/comic/detail.series?productNo=12146583), [Ridibooks](https://ridibooks.com/books/3498025206), [Bomtoon](https://www.bomtoon.com/detail/bookboo), [Lezhin](https://www.lezhin.com/ko/comic/my_namju), [MrBlue](https://www.mrblue.com/webtoon/wt_000069717)
