On her way to the east building library to find some reference books, Catarina joins up with the usual gang, and they decide to have a study session together. Then she opens a book that caught her eye... and it suddenly fills the room with light, then swallows her up along with Geordo and the others. Only Mary and Maria are left behind, so they cautiously open the book to try to rescue Catarina and the others trapped inside.

Anne Shelley is Catarina's personal maid, and is dedicated to serving her every need around the clock. Catarina is always surrounded by friends and laughter, but she's completely oblivious to the feelings that they have for her, which seems to have caused some misunderstandings. With no knowledge of how much Anne worries about this, Catarina decides to host Mary, Sophia, and Maria for a pajama party.

Catarina is suddenly faced with her own "judgment event." The cafeteria is abuzz, leaving Catarina's mind in a panic as she suspects her doom flag has been set at last. Then Geordo appears with the members of the student council. The noble girls continue to condemn Catarina as the student council members read the evidence they compiled against her. Then Maria, the alleged victim, speaks...

There's still no sign of Maria anywhere, and now Catarina has fallen into a deep sleep during which she dreams of her past life. Meanwhile, Geordo has a doctor examine her, but is disheartened when no cause can be found. As Catarina continues to sleep, all of her friends come to terms with their own feelings.

Catarina and the others have found the imprisoned Maria, and at last they confront the one behind her disappearance. How will this confrontation end?! Catarina has worked so hard to avoid her own doom flags all this time, and now she faces a crisis! And then the final event in the game, the graduation party, begins. Will Catarina make it through to the end without setting any doom flags?!
