I am Lu Ze, an ordinary architectural designer. My life was going as planned until a distant relative passed away unexpectedly, and my 4-year-old Niannian became my guardian. In the rush of raising a baby for the first time, I met Su Wan at the "Wanfeng Dessert Shop" downstairs in the community - she looked like a little money addict holding a ledger to calculate costs, but she would hand over a free piece of strawberry cake when she was crying.
In order to help Nian Nian adapt to the new environment, I became a frequent visitor to the dessert shop, and unexpectedly reached a "cooperation" with Su Wan: I helped her design a new display cabinet for the dessert shop, and she prepared healthy afternoon tea for Nian Nian every day. I thought it was just a mutually beneficial transaction, but as we got along, I was moved by her seriousness in settling accounts and her tenderness towards Nian Nian. But just as my heart was beating, Su Wan's former partner Zhang Hao suddenly appeared and proposed "high-priced cooperation." I was keenly aware of the calculation behind his eyes, and Su Wan was also swinging between interests and vigilance.
