Xia Chengan was diagnosed with moderate depression at the age of 17.
Just as she was preparing to face her death, a boy holding a drawing board illogically appeared next to her.
The boy's name is Xu Yi. He is allowed to be at ease, but cannot be at ease.
Time and space intersected, and fate made them at different ages meet each other, but fate made them miss it again.
Meeting again and again, missing again and again, forgetting again and again, remembering again and again, formed the mottled light and shadow under the sycamore tree.
Xu Yi, where are you?
Cheng An, I can't find you...
In a world without each other, where should we go?
