Lin Wei, a 32-year-old real estate project director, is trapped by the dual pressures of "requiring proof of marriage to obtain interest rate discounts for first-time properties" and "decreased ovarian reserve function"; Chen Mo, the design team leader, urgently needs a "marriage" in order to allow his mother with heart disease to operate safely. The two requests for each to get what they needed gave birth to a ridiculous marriage agreement.
From the first time playing "husband and wife" in the hospital, to the arguments and honesty on the eve of the defense; from jointly sketching the ideal blueprint of the retirement apartment in the open space on the outskirts of the city, to the tacit understanding of day and night collaboration in the boarded house, this contract that began with utilitarianism quietly deteriorated in countless warm details: a rented marriage certificate finally exposed the two people's disguised selves, and allowed them to gain sincere emotions beyond the contract and a new direction in life based on worldly standards and inner perseverance.
