Jane Hamilton is a kind and virtuous single mother. From the perspective of a mother, she is a great success. Her elder daughter Holly and younger daughter Zoe are growing up healthily under her careful care. Jane is not only their mother but also their friend, and the family life of these three women is full of joy. However, as a woman, Jane's emotional life is at a loss. Whenever a man appears, the lives of the three begin to become unstable. The most worrying thing is not Holly in adolescence, but the mother who is about to reach forty. In Holly's eyes, she has long understood her mother's emotional pattern: start a relationship with a not-so-great man, the brief sweetness soon turns into an inevitable breakup, then after the breakup, Jane will leave the place of sorrow as soon as possible, moving to another city with Holly and Zoe, hoping that the next man will be different from the previous ones.
Thus, Jane's love goes on and on, and the two daughters also live a wandering life with her. As Holly is about to become an adult, she urgently hopes they can settle down somewhere, like the peers around her, to attend school dances without distractions and lead a normal life. Holly does not want her mother to repeat the heartbroken romance anymore. She thinks her mother should recognize her charm and advantages, and that love is not the only source of happiness.
Holly keeps thinking about the best person for her mother to date. Who can prevent the recurrence of heartbroken love? When Jane's another romance ends, Holly begins to realize the urgency of time. She must immediately formulate a plan to create a suitor for her mother - a surprisingly super-perfect man. This is the only way to save her mother's feelings.
Holly must take action now because her mother's colleague, the unlucky but kind-hearted baker Ronny, is becoming the new suitor. Holly finds that the fake emails, letters, and gifts she fabricated no longer have an effective calming effect. Her mother starts to be annoyed by Ronny's 80s-style foolish courtship. In a hurry, Holly asks her friend's uncle Ben (Chris Noth) to pretend to be a "hidden" admirer of her mother. Long-term correspondence has made Jane believe that he is a gentle and charming restaurant owner.
However, contrary to Holly's expectations, maybe Ben is too charming. The makeshift plan devised by Holly and her new partner Adam and Ben's niece Amy becomes increasingly uncontrollable as their relationship progresses. Holly is increasingly troubled by how to continue the lie. For her, the most important thing is to make her mother happy and let them settle down. But Holly's troubles remain thorny. She has invested too much thought into the plan, almost missing her own super-perfect man...
