Summary
Upon entering the clubroom, Kodaka was dragged by Sena all the way behind the school. There, Sena spoke with Kodaka about the misunderstanding her father had about the two of them dating, and how Sena wanted Kobato to be her little sister; leading to marriage, much to Kodaka's dismay. Leaving the other matters aside, Sena reveals to Kodaka that they are both engaged, which was agreed upon by their fathers since they were young. At this point, Sena shows Kodaka a picture of them both playing together when they were young children. Though fascinated by this, Kodaka ensures Sena that they should both ignore the fact that they're both engaged - which was agreed without their consent. Though reluctant, Sena agrees and added that she will have Kobato as her sister without ever marrying Kodaka, much to the latter's dismay. Before returning to the clubroom, Kodaka notes to Sena that they both shouldn't inform the others about their dilemma.

Returning in the clubroom, as Kodaka gives thought about Kate's words after Kobato's birthday party, Maria reveals to the others about Sena's and Kodaka's engagement. With nothing more to hide, Sena and Kodaka reveal to the others that they indeed are engaged and the fact that they're childhood friends. Puzzled, Rika tells Yozora that a fiancee has a deeper relationship than that of childhood friends, but then added that Sena and Kodaka already met each other in the past; making them childhood friends also. Sena, annoyed by Yozora's and Rika's exchange, slapped some sense into Yozora and declares that they should begin filming immediately. When Yozora was about to leave the club room, she declares that she doesn't care anymore and the Neighbor's Club officially started filming afterward.
