Guan Wen rose through the ranks in a foreign company. But just before her birthday, Guan Wen was framed by her inferiors and lost her job. It is said that when you are over thirty and have accumulated a lot of experience, you can choose any career you want but Guan Wen had a hard time finding a new job. After failing many interviews, she had to choose a job inside a mall that just opened. Guan Wen ran into her ex-boyfriend, Ding Ning, who is cold and ruthless in his career. He is very critical of her. In their work together, the relationship between them changes from dispute to ambiguity, and from getting better to break up. There are many adult measurements and considerations involved. Meanwhile, two girlfriends of Guan Wen, Chen Xuanxuan, a retired athlete, and Jing Zhiqiu, a has-been actress, also confront their mishaps in life. So how do they fight against these challenges in life? If life is like a battle, they are their own best weapons.
Employée modèle, Guan Wen attise les jalousies et devient la cible de ses subordonnés. Victime de leurs attaques perpétuelles, elle n’a d’autre choix que de partir. Convaincue qu’elle trouvera rapidement un autre emploi au vu de ses compétences, Guan Wen essuie pourtant de nombreux refus et finit par travailler dans un centre commercial. Son moral n’étant déjà pas au beau fixe, elle se retrouve encore davantage dans l’embarras lorsqu’elle revoit Ding Ning, son ex-petit ami. Désemparée, elle se tourne vers Chen Xuanxuan et Jing Zhiqiu, ses deux meilleures amies, qui elles aussi doivent faire face aux difficultés de la vie.
