Episode 10 of "Hoshikuzu Telepath" deals with the aftermath of the bottle rocket championship and the emotional impact on the characters. The episode begins with Umika being praised by her class representative for her efforts in the championship. Haruno approaches their teacher, Emihara, prompting Umika to leave class to talk with her. Umika is worried about Matataki, who hasn't shown up for class.

Emihara shares her observations after the competition and notices Umika's determination not to give up despite the defeat. Emihara reveals that Matataki's tutor informed her that Matataki won't be coming to school for a while, likely because she's upset about the competition's outcome. Emihara senses that Umika understands Matataki's deep disappointment and asks Umika to ensure that she, Haruno, and Yu support Matataki.

Umika, Haruno, and Yu discuss visiting Matataki to cheer her up. Meanwhile, shaken by the recordings of her speech, Umika decides to confront her mistakes and improve. The next day, the trio visits Matataki at home, but she doesn't respond. Haruno makes a remark about the possibility of Matataki never returning to school but quickly takes it back. Yu uses her empathic abilities to sense Haruno's deep fears and doubts.

Haruno recounts a past experience where a friend gave up on their shared dream of becoming a pianist after a failed competition. This experience shaped Haruno's philosophy of valuing the journey regardless of victory or defeat, but Matataki's situation challenges this belief. Umika reassures Haruno that their dreams are still alive and expresses her desire to participate in next year's championship.

In a flashback, Haruno discusses her struggles with her grandfather, who advises her to support others' dreams. In the present, Haruno internally rejects this role and instead wants to work toward and achieve her own goals.

Later, Haruno visits Matataki and tries to encourage her to return to school. Matataki expresses her frustration at Haruno and asks her to leave. Haruno confronts Matataki about her behavior and explains that she wants to help everyone achieve their dreams, which diverges from her earlier ideals. Haruno takes Matataki's glasses as she leaves and urges her not to give up. The episode ends with Matataki alone, feeling misunderstood by the others.
