Notebook

 * We heard the story from Ilya, Rixia, and Avan. Let's return to investigate as soon as we can. (If refused at first)
 * We heard the story from Ilya, Rixia, and Avan. (If accepted at first)
 * We went to Ilya's apartment to investigate. First, let's check for damages.
 * From the looks of the door and keyhole, it seems like someone broke in.
 * Let's look for the criminal by questioning the other people who live in this apartment building.
 * Questioned Miss Sammie, the maid.
 * Questioned Mr. Kendall, who lives on the second floor.
 * Questioned Miss Brigitta, who lives on the second floor.
 * Questioned Mr. Levick and Miss Olga, who live on the first floor.
 * Found some damage near the apartment's rear entrance. The criminal may have entered here.
 * Finished questioning residents. Let's sort our evidence in Ilya's room.
 * We hatched a plot to ambush the criminal.
 * We caught the stalker!
 * He yearned for Ilya's way of life, but she only scolded him for it. He seems to have the agility and talent of a dancer, so Ilya decided to take him in!
 * It turns out the stalker was a girl. I wish I hadn't written this in ink.
 * Addendum: That girl, Sully, is now a member of the troupe and is doing just fine. (When speaking with Sully after finishing the quest)
