However, Riki learns that Yuiko is the only other person who knows the truth and she claims that it all is her fault.
Her wish for staying with the Little Busters forever had been granted in the form of a dream, and she tells Riki that she only knew what happiness was after meeting Riki and his friends.
Yuiko tells him that things will return to normal when he wakes up from the dream, but Riki will forget everything that happened.
Before bidding farewell, Yuiko warns Riki to take care of Rin, as the "fated day" is at hand.
Members of the Prefectural Assembly are expected to make an inspection at 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 get so impressed with her that they invite her to take part in a student exchange program, as part of their plan to help the students of another school to overcome a tragedy that claimed the lives of some of their classmates.
On the eve of Rin's departure, Riki realizes that all the tasks they received helped her to mature and improve her confidence, concluding 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 "secret of the world" he mentioned in his letters.
After waking up, Riki learns from Yuiko that she was taking care of him while he was asleep and cannot shake the suspicion that the whole situation has happened with them in the past.
Wondering if he is actually in love with someone, Riki does as they say, but ends up alone with Yuiko by accident when the fireworks begin.
The following day, Riki realizes that the same events of the previous day are being repeated as the date is also the same, June 20.
Suspicious of a girl who was overhearing them, Riki follows her and finds the same girls Yuiko had noticed the other day in a classroom, figuring that they are the culprits.
Despite being confronted by Riki, the girls claim that there is nothing he can show without any evidence of what they did, until Yuiko appears and plays a recorded conversation between them that proves their involvement.
