She had recently been adrift, a soul unbound by convention, when fate brought her across paths with a man burdened by misfortune. Their meeting, unplanned and serendipitous, occurred on a road leading to the coast. Soon after, they found th…

Kaito’s girlfriend arrives at Diamond Head, as does Hiromi’s former partner. Later that night, Kaito discovers that Hiromi had once pursued swimming with dreams of Olympic glory.

Kaito returned to his company, ready to dedicate himself to the project. Meanwhile, Hiromi journeyed to Tokyo, intending to perform a kindness for Masaru, only to discover an unforeseen presence in his vehicle.

Kaito’s old employer came to the guest house, seeking an explanation for the young man’s sudden abandonment of his profession. Meanwhile, Makoto discovered that Masaru wished for her to meet her mother.

He stood at the foot of Diamond Head, announcing himself as the swimmer who had taken Hiromi’s place at the Olympics. He declared his intention to resolve their dispute with a race.

As the annual fireworks display approached, a shadow of disappointment fell upon Kaito; Sakura had declined to attend. Meanwhile, Haruko carefully repurposed a faded summer robe, crafting a gift for Makoto.

Masaru often has a visitor named Michie, who upon arrival swiftly assumes command. She directs everyone to help with the tidying of the guest house.

With summer drawing to a close, Makoto feels a growing unease at the thought of Kaito and Hiromi departing. Sensing his apprehension, Kaito suggests he tutor one of Makoto’s classmates who is having difficulty with the material.

A letter arrived for Haruko, bearing the news that her ex-husband intended to bring their son to her. The missive also contained a stark revelation: he had not yet disclosed to the boy the truth of her being his mother.

The guest house quieted, and Masaru invited Hiromi and Kaito on a fishing excursion. Meanwhile, Haruko gently urged Makoto to consider contacting her mother, with whom she had long been estranged.

Masaru tried to surf again, but the wave overwhelmed him, and he tumbled into the water. Hiromi and Kaito offered their encouragement as he started training, determined to ride a wave once more.

The future of Diamond Head hangs in the balance. Hiromi and Kaito commit themselves to following Masaru’s counsel, while Haruko reaches a decision regarding the guest house.
