Lin Shen has been able to smell things that others cannot smell since he was a child - the smell of fear seeping into the wood, the bitter smell of rust mixed with rain, and the smell of disinfectant remaining in the fingers of the murderer. She has autism, and her senses are so hypersensitive that she is like a door that can never be closed. All sounds and smells come in, and she has nowhere to hide.
But she also has another kind of "supersensitivity": close her eyes and enter. She can "become" a murderer.
Purpose: Anti-domestic violence, female dominance, inheritance
