In order to help her best friend find her mother, Su Nian "married" herself to her best friend's father. I thought they were going to live together, but I didn't expect: Mr. Lu, who is "pure and stoic", is a maniac who dotes on his wife; his underage best friend is a great helper in helping her "empty the family property"; even her ex who wants to get back together is tortured to the point of collapse by her "brother".
