When San Francisco detective Monica went on vacation to Almafi, Italy, she met pianist Masaki Nagai who was working at the Almafi Music Festival. I thought it was just a chance encounter, but I didn't expect that several mysterious cases would combine their fates. They have become a detective team like Sherlock Holmes/Watson and a teammate who mocks each other but is somewhat ambiguous.
Monica gave Masaki Nagai a code name, "Professor Snape"
Monica: Hello, Professor Snape. Is there a new case?
Nagai Masaki: If I don't encounter a case, how can I meet you?
Concept: Teammate love slowly emerges in suspense and mystery
