Kyon, Taniguchi, and Kunikida visit their school cultural festival, including Mikuru and Tsuruya's class's food stall. While Taniguchi checks out the girls visiting from other schools, Kyon goes to watch the music concerts. Bored, he becomes sleepy. One of the amateur bands walks onto the stage with Haruhi and Yuki. Haruhi sings in a voice that Kyon comments to be talented, yet there is one discrepancy: Haruhi is reading off the sheet music. After singing four songs, Haruhi informs the crowd that the three-member band were unable to have their lead singer/main guitarist present, and so Haruhi and Yuki are acting as stand-ins. Later, Haruhi tells the full story to Kyon: the leader caught a fever and was not allowed to play by the student council, and so Haruhi and Yuki volunteered to replace her. The actual band members come to thank Haruhi, who becomes stunned and confused, leaving Kyon to think to himself that she has not experienced being thanked for anything and wonder if she could be happier using her talents to help people. Haruhi is upset that Kyon won't say this to her aloud, but soon becomes more focused on starting her own band with the SOS Brigade.

Love at First Sight
ヒトメボレLOVER

An old middle school friend of Kyon, named Nakagawa, calls Kyon, telling him that he is in love with Yuki. Feelings he is unworthy to approach Yuki at present, Nakagawa asks Kyon to send her a message: Nakagawa has his life planned out for the next ten years, after which he will propose to Yuki, and he wants her to wait for him. Kyon writes this down and presents it to her the following day. Yuki declines Nakagawa's request, saying that due to her commitment to the Data Overmind she may not be at liberty in ten years. Kyon realizes that he can't stand anyone getting in between him and the girls of the SOS Brigade. He crumbles up the paper with Nakagawa's love confession and throws it out the window; it lands at Haruhi's feet. She thinks Kyon and Taniguchi are pulling a prank on Yuki at first, but immediately believes Kyon when he tells her the truth. After Kyon gives Nakagawa Yuki's response, Nakagawa says Yuki may change her mind if she sees him play at his American football game. Yuki accepts the invitation, but Haruhi insists on bringing the entire SOS Brigade. Yuki recites an "incantation", causing Nakagawa to suffer an accident during the game and be wheeled out in a stretcher. After Yuki visits him at the hospital, Nakagawa tells Kyon the "glow" he saw in Yuki is no longer there. He is apologetic about his seeming fickleness but says he must withdraw his offer of love. When Kyon questions Yuki, she reveals that when Nakagawa first saw her, he was actually seeing the Data Overmind and interacted with it. The existence of the Entity overwhelmed him. Yuki's incantation removed his ability to interact with the Entity. Kyon asks her if she was disappointed that Nakagawa's infatuation with her was based on a misconception. Yuki replies, "...a little bit".
