(Fan of the Crime Hunting Illustrated Book) If You Were the Sister of Ducheng Shen Yi

You are a girl that Ducheng rescued from a criminal den. Unfortunately, when you were rescued, all your memories were lost because your life experience was not investigated. After discussing with Shen Yi, Ducheng made the decision and registered it in their household registration. In this way, you had two brothers. I thought that life would go on like this, but I didn't expect that your teacher Fang Kaiyi would recognize you later and involve you in a crisis. Concept: black and white, bright and dark
