Three years ago, Lin Xiaoman and Shen Yizhou were the "model group" among college couples. They went to the library together, went to the snack street, and even wrote three books full of graduation travel strategies. But just before graduation, Shen Yizhou suddenly disappeared, leaving only the sentence "We are not suitable", which made Lin Xiaoman emo for more than half a year. Three years later, Lin Xiaoman became a well-known interior designer. It was common for him to stay up late and revise plans, just to make a name for himself in the industry. Unexpectedly, the person in charge of Party A for the big order the company received turned out to be Shen Yizhou! What's even more outrageous is that when Shen Yizhou saw her, his eyes were full of strangeness, and he politely said, "Designer Lin, I have long admired your name." Lin Xiaoman was confused on the spot. What kind of fun was this? Later she learned that Shen Yizhou suffered an accident three years ago and lost all memories of her. On one side is Party A's father who is always picky and demands "the utmost control of details", and on the other side is his ex who he once loved to the core. Lin Xiaoman repeatedly jumps between "making money is the most important thing" and "unforgettable old love". Although Shen Yizhou didn't remember Lin Xiaoman, he always felt an inexplicable sense of familiarity in his heart when he saw the drawings she designed and heard her complain about the plans.
