Halloween Night. R-18, One Shot

This is a collection of short stories and one shots based off of the characters Gu Hai and Bai Luo Yin from the Chinese Web Series "Addicted/Heroin" and the novel "Are You Addicted?"
I do not own the characters, and will credit those who suggest a plot to me with each chapter! If you have any suggestions I will be more than happy to write it.
