Summary
Kodaka heads to their clubroom. There, he is greeted by Sena, whom Rika had informed of Kodaka's arrival prior notice. After mustering up the courage to give Sena his reply to her confession, both Kodaka and Sena's phone received a message from Yozora with the text stating she had gone on a 'journey' and asks to not search for her, much to their surprise. Failing to get in touch with her through calling, Rika arrives in the clubroom informing that she too has received Yozora's mysterious text message and asks Kodaka to send Yozora a text instead. After a dubious reply, Kodaka discovers that Yozora had witnessed his encounter with Rika on the school rooftop. Rika then personally calls Yozora on her phone to no avail, causing her to vulgarly lash out at Yozora for being unreasonable and weak-minded. Sena soon comes to the realization that Yozora might not have gone too far on her 'journey' with Rika and Kodaka agreeing as well.

Afterward, Sena demands of Kodaka for his answer to her confession, with Rika being asked by Kodaka to stay present as well. Kodaka declares to Sena that he loves her but abruptly states that he can't go out with her. Kodaka also made it further to the point of intending of doing sexual acts with Sena such as fondling and playing with her breasts, much to Sena's molestation, but Kodaka still infers that he can't go out with Sena in the hopes of protecting the Neighbor's Club's existence. After constantly trying to persuade Sena by kneeling and begging to her, Sena reluctantly accepts out of her love for Kodaka. Kodaka then thanks Sena for her understanding as he claims to himself that his first battle as a useless protagonist ended with a spectacular victory.
