A Marriage Contract with Two Husbands

Roselaine married Grand Duke Melchior, the best knight in the Empire. He said it's because, "I want to save you." Roselaine can only respond, "You don't know anything about me."A man who wants to save her life, save her family, pay off her debts, and even marry her? They say there's no such thing as a favor without any strings attached, so why would he go this far for someone he doesn't even know?"Because you look like someone I knew." Roselaine evidently looks just like Melchior's first love.While depressed because she thinks she is only a stand-in for his first love, Roselaine takes in Julian, who looks exactly like her husband's childhood self, as her disciple. But then Julien asks, "Please divorce him and marry me, Roselaine."What happens if she marries both men?
