Twenty-six-year-old Tong Yu is a survivor of twenty years of crawling and rolling in the mud. When she was six years old, Bai Shutong's world suddenly collapsed - her family was separated and her best friends were far away. She fell from the greenhouse into the wilderness. In order to survive, she kept her name anonymous. She had done the most tiring work and suffered the deepest cold. She had already sealed away the past of "Bai Shutong".
In the warm breeze of Kyoto, she returned with a new identity, but accidentally ran into a network called "Searching". Her family members looked around with belated guilt, her old friends never gave up looking for traces, and the bonds she thought had been severed long ago never dissipated.
There is no bloody revenge, no lingering love, only a woman walking through the darkness alone, in a familiar yet unfamiliar homeland, facing belated care and guilt, re-examining the pain of the past, learning to reconcile with her former self, and finding a place of peace of mind for "Tong Yu" and "Bai Shutong" in the noisy world.
