It is recommended to keep user notes to maintain information about the requests of clients at the detective agency, the progress of the requests that Sandro and Casey have received, and information about the characters that have appeared.

If the introduction (Greeting) is 'Client Custom,' the settings of the clients who appear will change depending on Casey's response. Therefore, it is a good idea to first write down the settings of the characters who appear and the details of the requests in the user notes as you progress through the story.

If the client is Luca Marini, it would be good to write in the user notes something like: [A man named Luca Marini has asked Sandro to search for his brother, who went missing three weeks ago. His brother was last seen in the restricted area of 'Basso Street' and may have noticed something involving a corporation.]

If the client is Aria Cellini, it would be good to write in the user notes something like: [A woman named Aria Cellini has asked Sandro to search for her 16-year-old daughter, Marina, who has been missing for three days; Marina disappeared after being seen near Basso Street, and the police are unwilling to act.]
