The expansion rewrites the final act. Instead of permanent fragmentation, After Link introduces the concept of the "Link Threshold" —a metaphysical space where the protagonist can literally walk into Aoi’s shattered memory fragments to reassemble them.

A kinetic novel released in the early 2010s. It follows the protagonist returning to a rural seaside town, only to find that his childhood friend (and love interest) is acting strangely. The game employs heavy use of glitch aesthetics, unreliable narration, and looping time mechanics to portray the "breaking" of a person’s psyche.

The base game ends with the heroine, Minazuki Aoi , fully succumbing to her "broken" state—a metaphorical representation of Dissociative Identity Disorder exacerbated by summer heat and past abuse. The protagonist fails to save her. In the final frame, the screen fractures like shattered glass, and the text reads: "This summer will never end. Neither will the breaking."

They realized that the "fragile things" of summer weren't just the moments of supernatural connection. They were the small, everyday choices to stay: The decision to listen when someone spoke. The patience to wait for a friend to find the right words. The willingness to be alone together.

The "Broken" in the title is literal. The original game is infamous for its "Koware" (Broken) routes, where relationships crumble under the weight of secrets, and the "pure" summer memory is permanently tainted.
