The Marquis Couldn't Have Children, So I Turned Around and Became the Top Scholar's Live-In Son-in-Law

On our wedding night, my husband brought me a bowl of infertility medicine. "Tingxue, my sister-in-law is gravely ill. She hopes we can adopt her two children as our own." He sighed. "So that you can love those two children as if they were yours, you can't have children of your own. My elder brother died saving me. We have to repay that debt." My husband's widowed sister-in-law, who was seriously ill, wept like a flower drenched in rain. "Sister-in-law, the children are so pitiful. Please, have a little compassion." I smiled at her. "Sister-in-law, just because I can't bear children doesn't mean the Marquis can't have them with other women. Only if the Marquis himself is unable to have children will your two be the only children in the marquis's household."
