Fei Lanlan is an ordinary woman. She doesn't have extraordinary looks or much talent. She can disappear in less than three seconds if she is thrown into the sea of people. But her heart is extremely delicate and sensitive. She often jokes that her soul is incomplete and she cannot breathe normally. But she has a happy family, and at least many people envy her. She is already the mother of a three-year-old boy. She has a husband who loves her very much, but she doesn't know whether the relationship with her husband is love. Because she could never forget the person buried deep in her heart and the bitter love. That self-acting one-man show consumed almost all her emotions.
She thought she would never meet that person again, but the gears of fate meshed again, and the emotional whirlpool once again eroded her. Faced with love and family, conspiracy and betrayal, can that incomplete heart survive strong again?
