Let's Be Partners for the Rest of Our Lives

After a one-night stand with Ji Yanshu, a powerful CEO, the quiet office worker Yu Duoduo finds herself unexpectedly pregnant. Pushed by Ji's family elders, the two enter a flash marriage — one built on responsibility, not love. Ji Yanshu, still bound to his longtime girlfriend, promises they'll divorce after the baby is born. But as life weaves them together — through quarrels, care, and quiet nights — their hearts begin to change. When old love returns and secrets surface, Duoduo must decide: walk away as planned, or risk everything for the man she never meant to love.
