Wen Zhixia is a restorer of ancient books. Her life is like those fragments of books that need to be repaired. They seem to be complete but are actually full of cracks. In order to find a peaceful roof and avoid the endless entanglement of her original family, she chose a transaction that had nothing to do with love - marrying Fu Yanshen.
Fu Yanshen, a well-known architectural designer, is famous for his calmness, rationality and precision. He built countless magnificent landmarks, but created an airtight spiritual island for himself. In order to withstand family arrangements and outside disturbances, he needs a wife in name only, a quiet and measured "share tenant".
One contract, two worlds. He gave her shelter and she gave him peace. They are the most familiar strangers under the same roof, using politeness and distance to establish clear boundaries.
However, when the light in the study room late at night reflected her focused silhouette while repairing the fragments; when the warm aroma of food floated for the first time in the cold and empty villa; when she accidentally glimpsed the fatigue and scars under his calm mask; when he subconsciously defended her when she was being made trouble... The boundary called "contract" was quietly eroded without her realizing it.
This is a story about healing and being healed. He used his world to protect her from wind and rain, and she used her gentleness to bring the first ray of warm sunshine to his cold island. When the contract came to an end, they discovered that the marriage that started as a transaction had already turned into an unforgettable love under the slow cooking of time.
