To pay off her family's debts, Shen Zhili is sent to the Ke family and married to their young master, a man rumored to be terrifying. At their first meeting after the wedding, he says only one word to her. Everyone warns her not to provoke him, but she gradually discovers that this man, whom everyone avoids, has an absurd number of rules, yet not a single one is meant to restrict her. He never says he loves her or explains himself, but her life quietly begins to change. From being too afraid to raise her head to daring to argue with him; from desperately wanting to escape to finding herself reluctant to leave. A marriage that began as a mutually beneficial arrangement slowly grows into genuine love.
