The quiet hum of the coffee shop offered a solace to Solo, battling the familiar grip of sleeplessness. It was closing time when he encountered Gui, the barista, and the warmth of a shared drink ignited an unexpected connection.

At the hospital, Gee hurried to his foster mother's side, the echo of her last words lingering like a profound impression.

Lost in grief, Gee sought solace in the quiet countryside. It was there he encountered Moon, a child whose presence offered an unexpected and profound warmth.

Alone, Gee, and Moon find solace in the wilderness, their connection deepening with each passing moment. It is during this time that Gee stumbles upon a letter, its contents hinting at a revelation capable of reshaping their world.
