I Married into a Marquis's Household as a Widow. When My Husband Returned, My World Fell Apart

After transmigrating into the body of a timid, unlucky official's daughter, she is about to be married off by her aunt to an old man as his second wife. Xi Yunxiu chooses to carry her betrothed's memorial tablet and marry him, even though he died in battle. She'll guard the sprawling marquis's residence and enjoy life as a rich, happy young widow. But there's a biased mother-in-law, sisters-in-law with their own agendas, and a sensitive, suspicious adopted son... Xi Yunxiu scoffs. The strong don't complain about their circumstances. They change them. Before long, her biased mother-in-law can't go three sentences without saying, “We need to ask Third Daughter-in-Law about this.” Her sisters-in-law are united: “We'll all follow Third Sister-in-Law's lead!” Her adopted son keeps saying, “I love Mother the most!” Even her late husband's former rival comes rushing to her door to win her favor. And just then, her late husband returns!
