Summary

Lady Tiziano, once a knight and now a jilted ex-fiancée, is rejected by the man she once loved for being "too unladylike." But just as heartbreak sets in, the Duke she secretly admired offers her a marriage proposal. Things seem too good to be true—and on the day of their wedding, Tiziano overhears that the duke may already have… a lover? What started as a way to get back at her ex takes a turn… into a sugary, overly affectionate romance she never saw coming!? She wanted revenge, not affection. She wanted pride, not kisses. But maybe—just maybe—she’ll find real love anyway.
