Mr. Sahara & Toki-kun

After the festival, Kanade finds a scrapbook about Sahara’s past as a national-level swimmer and Olympic hopeful. Curious, he asks Sahara about it, but Sahara suddenly grows cold. Meanwhile, Kanade learns a secret about the Todo brothers, and Sahara, sensing the inner struggle of the elder brother Shinji (Daiki Matsumoto), begins to reveal his own emotional history.

To keep Shinji from competing in basketball while injured, Kanade headbutts him to force a break. In the nurse's office, Shinji reunites with his stepbrother Takuya. Meanwhile, Sahara takes Kanade to a lakeside and opens up about his past, revealing deeper feelings for Kanade in a moment of quiet honesty.

Minato unexpectedly confesses to Sahara. In high school, Minato had turned down Sahara’s feelings, fearing he’d be a burden. Even after graduation, he continued caring for Sahara from afar, especially after Sahara suffered a university injury. Sahara is shaken by the resurfaced feelings and unresolved past.

Kanade shows up to school injured, having held back in a fight with another school’s delinquents out of respect for Sahara’s wishes. But when they show up again, he prepares to face them alone—at the riverside, a place full of memories for both Kanade and Sahara. In this emotional final episode, the bond between teacher and student deepens in an unforgettable way.
