Su Xiao, an independent architectural designer, has a project dispute with Gu Yan, a real estate CEO who pursues efficiency, because he adheres to the concept of "green building". However, when Su Xiao was falsely accused of "plagiarism" by her colleagues, Gu Yan silently collected evidence to help her clarify; Su Xiao also modified the design plan to balance interests and ecology when Gu Yan's project encountered "environmental protection protests". On the day the project was completed, Gu Yan handed over a cooperation letter: "This is not a project cooperation, but I want to work with you to design your future home."
