Gaia and the Realization That Friendship Was the Foundation All Along
Brightness controls whether someone sees the hopeful side of a situation. Gaia had been looking at her life through a lens where the absence of a romantic partner meant something was missing. At the park with friends, that lens shifted — she stopped scanning for what she didn't have and saw, clearly, everything she did. The dial moved from dim to bright, and the same life looked completely different.
