Beware the Kamiki Brothers!

The scene opens with the two of them in the middle of a study session. They are interrupted by the arrival of Tachibana, who has just returned from a visit with her father. She asks the two if they are serious about their relationship. They reply that they are, and that they would like to study together in order to get to know each other better. They decide to take a break from their studies so that they can talk to each other privately.
