Als ein Schulinspektor der Präfektur die Schule besucht, wird beschlossen, dass zwei Freiwillige aus Rikis Klasse den Mann am Campus herumzuführen sollen. Riki und Rin erinnern sich an Lennons jüngsten Brief und heben vorsichtig ihre Hände. Rin gibt ihr Bestes, während sie den Schulinspektor herumführen, und obwohl sie offensichtlich nervös ist, findet der Mann ihr Verhalten bezaubernd. Nachdem er gegangen ist, wird Rin in das Lehrerzimmer gerufen...
Members of the Prefectural Assembly are expected to make an inspection of the school and realizing that it is part of the "final task", Riki and Rin volunteer themselves to guide them around. Despite Rin's shy demeanor, she manages to guide the visitors properly and they later invite her to take part in a student exchange program to help the students of another school overcome a tragedy that claimed the lives of some of their classmates. Riki at first asks Rin to decline their invitation, but he later realizes that this could be an important experience for her to grow as a person. However, when Riki tries to encourage her to take part in the program, she gets angry at him and ultimately accepts the invitation. On the eve of Rin's departure, Riki realizes that all the tasks they received helped her to mature and improve her confidence. He concludes that it was all a part of Kyousuke's plans, including inviting Komari and the other girls to become part of their group. His suspicions are confirmed when Riki finds Lennon with Kyousuke and then he confronts him about the "truth of the world" he mentioned in his letters. However, before getting some answers, they are forced to run away after being caught outdoors during curfew and when Riki trips over, Kyousuke disappears in front of him.
県議会の議員が学校を視察するので、理樹たちのクラスから案内役を２名出すことになった。
猫のレノンが運んできた手紙に「ホームルームに立候補しろ」と書かれていたのを思い出した鈴と理樹は、
恐る恐る案内役に立候補する。
人見知りの鈴はがんばって議員を案内しようとするが、緊張は隠せない様子。
ところがそんな鈴の不器用な態度がなぜか議員に気に入られてしまう。
議員が帰った後、鈴は職員室に呼び出され、思わぬ任務を要請される。
레논으로부터 건내진 마지막 과제. 그것은 조회시간 입후보하는 것이었다.
그 내용은 학교를 시찰나온 시의원을 안내해주는 역할을 맡는 것.
리키와 함께 무사히 안내역을 마친 린이었지만 이 일은 생각치 못한 방향으로 전개되고 마는데...
理樹班上要選出兩名同學負責招待來學校視察的縣議員。鈴與理樹想起信上的課題，於是自願擔任招待的工作。在議員回去後，老師把鈴叫到辦公室，對她說了令人難以置信的話…
