In this chapter, we are introduced to a young woman named Keita, who is engaged to a man named Rinko Suzuhara. The two of them enter into an agreement in which they agree to each other's demands and to rush to the side of the other. In addition, they agree not to divulge any information regarding their relationship with the other party. The agreement is terminated if the information is revealed to anyone other than the first party. Keita asks to be sent back to Ozawa's office, where she has been sent to retrieve some paper that has fallen from a crack in the wall.
