Manor of Amnesia

A man named Ken awakens in an elegant mansion with no memories of how he got there.

Supposedly, this mansion is his home, and the only other people with him in the mansion are a girl claiming to be his wife, and a young man working as a butler.
What secrets lie within his missing memories?
Will you pursue the answer to that mystery? Or simply live a happy life in this mansion?
This "world" shrouded in mystery is the stage.
Your own home, filled with memories that can either be remembered or forgotten.
