The episode begins with an unexpected encounter between Kouya and Haruka in a supermarket. Haruka, who had discovered Kouya's whereabouts through a business card in his apartment, is worried about his well-being and his lack of communication with mutual acquaintances. Kouya admits that he needs time to think. Haruka decides to stay with Kouya until he completes his unspecified task.

Kouya takes Haruka on a trip to the Sanriku Coast, starting with a visit to a seafood restaurant. They sample local cuisine, with Kouya encouraging Haruka to try various dishes. Afterwards, the duo visits several local landmarks, including a beach house and a rest stop, and tries regional specialties like oyster-flavored ice cream.

The two participate in a go-kart race, during which Haruka proposes a bet: the loser must do something for the winner. Despite having a three-lap lead, Kouya loses. Haruka asks Kouya to take a photo of him, which Kouya refuses due to his past trauma of photographing people.

Haruka confronts Kouya about the real reason for his aversion to photographing people. It turns out that Kouya's inability stems from a tragic event during an earthquake, where he failed to save a child. This incident left a deep mark on Kouya, haunting him and affecting his photography.

Kouya recounts his experiences during the earthquake, describing in detail the losses and destruction it caused. He explains how this event changed his perspective on photography and life. Kouya also talks about a controversial photo he took during the disaster, which brought him public criticism and personal guilt.

Kouya and Haruka visit Shouzou, an elderly man in the hospital, and realize that Kouya only returned to see him. Shouzou's family had previously denied Kouya visitation due to the controversial photo. Kouya and Shouzou share a moment of understanding and reconciliation.

Kouya reflects on the nature of photography and its impact, drawing parallels to a famous war photograph. He contemplates the ethical implications of capturing moments in time and the responsibility that comes with it.

The episode ends with Kouya and Haruka leaving the memorial hall, with Kouya showing a sense of determination and a willingness to move forward. Haruka supports him and suggests they return home, bringing their journey in this episode to a close.
