“Perhaps this is how I can finally repay you.” Natalia, the future head of an earl’s family, discovers her fiancé, the son of Duke Justus, in an affair with Luce, a girl who addresses her as “big sister.” Justus condemns Natalia as unlovable and inflexible, demanding to know why twins could be so different. Yet Luce is not her twin at all.
