In my previous life, I left behind three children and my husband, and died after a long illness. When I came to, I had been reborn as a duchess. I remembered the novel I read on my sickbed in my previous life, where the early villain mistreated her son and was killed as a result. Determined to shower my adorable son with all the love I couldn't give in my previous life due to illness, I decided to work with my husband, who neglects the family, to build a happy home. However, my husband turns out to have a heavy, first-love kind of love for me. Can I build a happy family...?
