This story begins with an online post called "Looking for Su Yinan". At that time, I was in the northernmost part of China. At night in H City, I felt the coldness of winter in my bones.
I sat under the steps of the Sophia Church, looking at the feathers left by doves during the day, thinking about that girl's smile that summer, and thinking about her words when her clothes were flying in circles: Su Yinan, look at how thin I am! From now on, you will be responsible for making me fat!
