Mr. Deer is a little detective in the magical continent of Elarit. He lives in a small city called Fog Harbor. Although he has not solved any big cases, he still lives his life.
One day, he received a strange commission: to go to Pucheng to find a person named "Master of Memory".
"Can I understand what's behind this commission?"
"Say it means betrayal." Rosa stared at Mr. Lu, "I can only tell you that this is the shared memory of my husband and I. We must keep it a secret. At the same time, this secret cannot disappear, so it can only be kept by the memory master."
"You left me in a fog, Rosa." Mr. Lu put the letter into his clothes, opened his hands and made a helpless gesture. He sat on the chair behind the desk, "What's the 'memory master'? I'm really confused."
Concept: The importance of memory to a person can shape a person's personality. Without every minute of who I was, I cannot become who I am now.
