Lin Zhixia and Gu Chenzhou were lovers in college, but were forced to separate due to misunderstanding and pressure from reality. Seven years later, the two met again during an urban cultural exhibition project. At that time, Gu Chenzhou was already a well-known architectural designer, while Lin Zhixia was a well-known illustrator. The two have an old relationship, but they are unable to get close because of the scars of the past. As the project progressed, they had to come into frequent contact, and their previous misunderstandings were gradually revealed. Finally, they found each other's warmest home between reality and ideals.
