Mitglieder des Neighbour Clubs haben begonnen, einen Film zu drehen, der auf dem Schulfest gezeigt werden soll. Die Szene von Yukimura und Maria wurde im Innenhof gedreht. Am nächsten Tag trifft Kodaka beim Spaziergang mit dem Drehbuch in der Hand ein Mädchen, das vor der Rangliste für die Abschlussprüfung den Namen von Sena, der Klassenbesten, anstarrt.
As the Neighbors Club get their film underway, Kodaka comes across Sena's classmate, Aoi Yusa, who considers Sena her biggest rival and believes Kodaka to be her boyfriend. Later that day, Kodaka comes across Pegasus, who had assumed he and Sena were dating and is shocked to learn that it isn't the case. The next day, Sena explains the confusion came about do to a comment she made about 'making Kobato her little sister', which he assumed pertained to marriage. She then reveals that both their parents had arranged at a young age for her and Kodaka to be engaged, as they had met once when they were really young. Kodaka decides they should just forget about it and keep it a secret from Yozora. However, Maria ends up blabbing about in front of everyone having learnt about it from Kate, which leaves Yozora completely depressed. After being recommended a movie by Kate upon hearing about the movie's plot, Kodaka discovers Yozora had completely plagiarized the script from the movie.
