August 31

August 31, the last day of summer vacation, is the date of Maori Hino and Tooru Kamiya’s planned fireworks outing and a turning point in how Maori experiences their relationship. Because her anterograde amnesia keeps her from carrying the previous day’s memories into the next, she has to reconstruct her life from written records. On this date, anticipation, recorded reminders, and the feelings of the present converge: Maori enjoys an evening with Tooru as his real girlfriend, then breaks into tears at the thought that the day—and what she feels—might survive only in her diary.

A Date Prepared by Earlier Selves

August 31 is already marked in Maori’s planner as the day she will see the fireworks with her boyfriend. She wakes to a yukata folded on her desk, prepared by the version of herself who lived through the preceding day. Beside it is a Post-it drawing of herself with the message, “Have enough fun for the both of us! Love, Yesterday’s You.” The note makes the daily divide between past and present tangible: yesterday’s Maori cannot accompany today’s in memory, but she can leave her a plan and a wish.

The date also gathers together the routines Maori has built to live with that divide. She reads her binder and journal to learn what she has arranged, then uses a video already chosen by a past self to learn how to put on and tie the cotton yukata. Her records do more than report events after they happen; they let earlier versions of Maori prepare practical help for the person she will be the next morning. The careful preparation gives the day continuity without giving her direct access to the memories that produced it.

Her plans are specific. The fireworks begin at seven, and she is to meet Tooru outside a station in a neighboring district at four. They hope to avoid the crowds and have time to talk. Izumi Wataya, whom Maori had invited, declines so that the couple can spend the last major event of summer together. The date thus begins as both a personal arrangement between Maori and Tooru and a prospect that Izumi deliberately leaves to them.

From Pretend Couple to Present Intimacy

The relationship has a written history that Maori must consult rather than remember. Her binder has a section titled “My Boyfriend,” and her phone contains a folder with the same label, filled with photos and videos of Tooru. One video, made while they ride together, shows him glancing back as he pedals and captures Maori’s flirtatious voice and their shared enjoyment. Watching it makes her smile despite her embarrassment at how giddy she seems in the diary. By August 31, these records have introduced Tooru to her again and again, but the date gives her a chance to experience him directly.

As the outing unfolds, Maori speaks faster than usual and feels embarrassed by her boldness, yet she does not want to leave anything unsaid or undone. Today’s self, she recognizes, will exist only for today. Walking hand in hand with Tooru, she feels that they are no longer behaving like a fake couple but like a real one. The movement from a relationship that began under conditions toward genuine intimacy is enacted through a small, ordinary gesture; the significance lies in the contrast between the label that brought them together and the closeness she feels now.

The evening becomes an intense concentration of shared experience. Maori laughs often and feels that they have fit a whole summer’s worth of memories into a single day. She feels naturally drawn to Tooru and experiences him as affectionate toward her. At the fireworks, they sit together on a riverbank. Although large crowds have usually made her uncomfortable, she finds comfort in being two insignificant people among everyone else. They watch in awe and hold hands tightly, sharing a public spectacle while inhabiting a private moment within it.

Fear of Forgetting

The fireworks prompt Maori to question what will happen to the feelings she has experienced. She wonders whether her emotions will vanish with her memories, whether they can take root without accumulating over time, and whether anything of this day can carry over to tomorrow’s self. The questions expose a limit that journals, photographs, and videos cannot simply solve: records can tell her what happened and show her how she appeared, but they cannot guarantee that tomorrow’s Maori will feel today’s attachment as her own remembered past.

Her response comes before she has time to reconsider: “I…don’t want to forget,” she tells Tooru, her vision blurred by tears. She does not want an important moment to exist only in her diary. The distinction is not between having a record and having no record, but between reading that an experience occurred and retaining it as lived memory. For someone whose days repeatedly begin with reconstruction, the fireworks make that difference painfully immediate.

The date therefore brings both fulfillment and fear into the same scene. Maori has what her preparations promised—a long-awaited outing, a yukata, time with Tooru, and fireworks watched together—yet the happiness sharpens her awareness that the day may not remain accessible. Her tears do not cancel the joy of the outing; they reveal its stakes. Precisely because the moment matters, the possibility of losing it feels unbearable.

Place in the Story

August 31 links the novel’s recurring practices of memory-making to a decisive emotional encounter. Earlier, Tooru wants to fill Maori’s journal with happy experiences so that the Maori of each following day can face ordinary life with more courage and less fear of the future. The planned activities—including the fireworks date—are thus not merely diversions: they are experiences that can be written down for her to read after her daily reset. The outing tests both the kindness and the limitation of that approach, since a journal can preserve an account but cannot ensure that the feeling itself accumulates.

The date’s details—yesterday’s message, the planner, the binder, the phone video, the yukata tutorial, and the time and place arranged for meeting—show memory being supported through objects and prior effort. On August 31, those supports make a shared day possible, but they do not remove Maori’s uncertainty about what remains inside her. Her plea not to forget marks a shift from preparing for the next day to wanting an experience to endure beyond preparation and documentation. The date matters, finally, because it makes the present relationship vivid while exposing the fragile boundary between a life recorded for tomorrow and a life remembered from within.
