Ten-year Marriage Puzzle

A woman can love, but leave a little room for herself. Ten years of marriage had made her a lady from a simple woman. His daughter was eccentric and his man's career was smooth sailing. In order to get married, she did everything she could think of. At the crucial moment when her husband was promoted, she went to find her ex-boyfriend to help him deal with his troubles, and from then on, she would work with him to protect this hard-won marriage. However, when she looked back, she realized that the day before she was to get divorced, fate had played a joke on her.
