The Frequency of Return
This article discusses an illustrated light novel adaptation. For the original outline, see Beach Surgery (story) and The glitch.
Major spoilers for the ending.
The Frequency of Return reimagines Beach Surgery as a psychological exploration of memory and identity loss, told through Leif's interior monologue and Katita's clinical case notes.
Premise
The light novel frames the narrative as a series of therapy sessions. A clinician interviews Leif about his three injuries: his inability to walk, his blindness, and his arrhythmia. Each chapter represents one week of recovery. But as Leif speaks, his account of events contradicts Katita's written observations. Her notes describe a different Leif: different habits, different memories, even different scars.
Structure and chapters
Chapters alternate between Leif's first-person recollection (introspective, fragmented) and Katita's third-person clinical documentation (precise, dated, skeptical of what Leif reports).
Week One: Leif recalls waking in an apartment. He remembers Katita unwrapping bandages from his eyes with great gentleness. Katita's notes: The patient claims I removed bandages. I applied them. He remembers a seagull made of metal and kindness. Her notes: The seagull was autonomous and hostile. The patient romanticizes events.
By Week Three, Leif has recovered enough to walk. He recognizes Newcastle from his memory—the car park, the preschool, the stone pool. But Katita's entries note that Newcastle contains none of these structures. The preschool was demolished in (████ ). The car park exists in a different suburb. Katita (written): “The patient is synthesizing false geography. Or he is remembering the place as it was, before the forgetting.”
In Week Five, Leif begins to doubt his own past. His memories feel borrowed. He asks Katita: Leif: “Did I ever know you at all?” She does not answer in writing. Instead, her clinical notes stop. The remaining chapters are entirely Leif's voice—increasingly uncertain, increasingly aware that every memory might be Katita's implant.
The revelation
The novel's final chapters suggest that Katita did not rescue Leif. She constructed him. His three injuries are not recoverable conditions; they are baseline states. He has never walked, never seen, never had a stable heartbeat. What he calls memory is narrative she has fed him during his therapy. The novel ends not with resolution but with Leif asking: Leif: “If I cannot trust what I remember, how do I know this question is mine?”
The glitch and two editions
The light novel's treatment of the glitch is unique: it proposes that the glitch is not in the story's structure but in the protagonist's reliability. The two halves cannot connect because one of them may not be real.
Records suggest two different final chapters exist. In one, Leif accepts his constructed nature and begins again. In the other, Leif realizes Katita has been asking him the same questions repeatedly—and he always forgets the answers. The cycle is not metaphorical; it is literal.
