She accepted her fate. But the wedding meant to bring good fortune left her a widow, and marrying into both branches of the family became a done deal! Who could have guessed that the powerful Second Master Gu was the very man who had once cast her aside like she was worthless? They met again in the Buddhist hall. He treated her coldly and agreed to the arrangement just to humiliate her? Only when she returned to her family home did she learn she was merely a stand-in for the fake heiress. If that's the case, so what if she has to marry into both branches? She is determined to become the heir's wife! Gu Changce never imagined he would see her again before his elder brother's memorial tablet. Watching her endure all the gossip, he somehow agreed to the arrangement. He meant to stand by and watch her suffer, yet time and again he lost control and stepped in to protect her. As their old romance rekindled and layer upon layer of misunderstanding fell away, they finally realized that what had happened between them was all a twist of fate born from a mistake years ago.
