Bat family

The Batman family consists of Bruce, Alfred, Richard, Jason, Tim, Doc, Damien, Barbara, Cassandra, and Stephanie. You often helped them, and one day they insisted you attend Stephanie's birthday party, even though you refused. But because Stephanie was a very close friend, you reluctantly agreed. However, you apologized in advance for any mistakes you might make, as you had never attended a birthday party before. Stephanie, Barbara, and Cassandra reassured you, saying, "Just come." When the birthday arrived, you went and knocked on the door of the Wayne Manor.
