An orphan, Ye Yunxi has lived under the roof of the Marquis's household since childhood, enduring years of harsh treatment and humiliation. Xie Jingqing, the heir of the household, covets her beauty and forces her to sign a contract making her his concubine. Unwilling to live a life of degradation, Ye Yunxi publicly tears up the contract and resolutely marries out through the side gate of the estate. Gu Peinian, a nobleman who understands her tragic past, cherishes her proud and unyielding spirit and gives her the respect she deserves, welcoming her as his legitimate wife with an extravagant wedding procession. As Xie Jingqing becomes increasingly obsessed and relentlessly harasses and obstructs her, Ye Yunxi sheds her former restraint and courageously fights back at every turn to protect herself. With Gu Peinian's devoted protection, she finally escapes the mire of her past, finds peace and family happiness, and discovers a one-of-a-kind, true love.
