He then reveals that the redevelopment plan is being pushed by a corporation owned by… the previous Miya’s family. She is now a real estate executive in Tokyo. She is coming to inspect the property in three days.
Miya (our protagonist) makes a bold decision. She will not let the past repeat itself. She will stand under the cherry tree and confront the older Miya face to face. The chapter ends on a powerful double-page spread: all six current residents standing in a row under the cherry tree at sunset. Miya is at the center, holding the diary above her head like a flag.

That same tree is now slated for removal because the redevelopment plan includes a parking lot.

The revelation hits like a thunderbolt. The quiet, world-weary manager was once the passionate boy in the diary. Miya confronts Manager Yamada in his office. He is sitting in the dark, smoking a cigarette (a rare mature moment for the manga). After a long silence, he admits: “That Miya was my first love. She moved away after her father got a new job. She promised to return. She never did.”
