Lawyer Mu Qian and mediator Ou Yang decide to divorce due to lack of trust and mutual understanding. They have been given 30 days of cool-down period before the finalization of the divorce. Since the nature of their work and different cases they work on, the two of them frequently met in the workplace.

While handling the divorce cases for some other couples, they come across the problems existing in their own marriage and realise the mistakes they have done. Can the two solve their problems in their marriage and fall in love again after 30 days?
