All the stories are revealed to exist within the same universe.

A mysterious bookstore contains every unfinished love story ever written.

The keeper of the store watches over shelves filled with lives that almost became something more.

When a customer asks why the books have no endings, the keeper smiles and replies:

"Because somewhere, in another world, perhaps they finally chose each other."

"For every love that never was."

Endings may give us sadness, but also a faint sense of hope—that maybe some missed chances find their way back in another life.
