A single misstep into a glowing rune changes everything.
When Diluc Ragnvindr and Kaeya Alberich are unexpectedly pulled through a mysterious rune, they find themselves standing in a version of Mondstadt that feels... lighter. Brighter. A world that mirrors their own yet carries none of its lingering wounds.
There, they meet themselves.
Not reflections twisted by illusion but versions of who they could have been. Brothers who chose to talk instead of turning away. Who faced grief together, healed slowly, and never let the word brother become a ghost between them.
Forced to confront a reality shaped by reconciliation, Diluc and Kaeya must face the weight of their own choices, regrets, and the silence that followed their fallout. As past wounds resurface and truths long buried begin to unravel, the line between what was lost and what can still be saved begins to blur.
This is a story about grief, forgiveness, and the quiet courage it takes to reach out before it's too late.
Because sometimes, the hardest world to face...
is the one where things could have been better.
