In my previous life, my husband and I stayed together for decades. Only when he passed away did I discover that his heart had always been fixated on someone else. I revealed the long-buried truth, only to learn that the woman he was obsessed with had long since died in a dry well. Reborn, I return to the marquis's residence and am shocked to discover that my husband has also returned with memories of his previous life. Driven by his selfish obsession, he secretly switches my identity with another woman's, hoping to protect her and give her a peaceful life. Using my memories of the past, I hold on to my true identity, untangle the disputes within the household, and uncover the tangled truth of our origins. I cast aside the wrongs of my former life and choose a worthy partner. Together with a young general, I face the dangers ahead and protect the peace and safety of those dearest to me.
