In 1925, in Shanghai, 8-year-old Lin Shuhe gave a 7-year-old "idiot" a candy and a name - Lu Zhizhuo.
She was the first ray of light that illuminated his chaotic world, and he became the silent shadow guarding her throughout his life.
From the ivy-covered orphanage to the turbulent streets of troubled times, his world is small and can only accommodate her. Her world is big, but she is willing to anchor it for him.
However, as the pendulum of fate slid towards his twilight years, the cruelest joke quietly came. The light that once illuminated him began to extinguish inch by inch in the long river of memory - Lin Shuhe suffered from Alzheimer's disease.
This time, it was his silent turn to be her whole world.
He held her hand as if making his first vow: "Ah He, don't be afraid. I will help you remember everything you have forgotten."
This is a clumsy guardianship that begins with glimmers of light and runs through troubled times, a love epic that spends the rest of its life fulfilling its only promise.
