Yi Ran thought that his favorite father since he was a child, such a graceful and elegant man, could raise a wife outside the house in the name of love. Even though he and his mother loved each other so hard back then, and her mother had worked hard for him over the years since they got married, and she loved him even more than herself. The warm relationship between her parents was just a sweet trap set by her father, who suppressed the pain of being in a scam. Until his father promised himself to the man with a reputation for romance for the bastard son of his wife, what kind of man could he expect his fiancé to be? But even so, he couldn't refuse, otherwise who would protect his mother and little sister? This is probably what she will do for the rest of her life, marry that man, have a child, and use her identity as that man's wife to protect her loved ones. But what kind of man is Qi Teng? This man has no expression on his face, but he always defends himself inadvertently. He wants to "use" his inexplicable favor to protect his family, but he gradually begins to include this man in the scope of the people he protects. But is this love?
