Daisy: How to Become the Duke's Fiancée

あらすじ

Sweet, timid Daisy meets a tragic end after being betrayed by the man she loves. When she is given a second chance at life, she vows not to repeat the same mistakes of the past! The only problem is that she must pay off her father’s gambling debt to Kilian, an aristocrat with a terrifying reputation. One option will take her 60 years, and the other, just three... but it involves a contract marriage to Kilian, who must be three years married in order to inherit the title of duke. While Daisy has sworn off men, the conditions of the offer are too good to pass up.
