"Everyone is supposed to find happiness eventually, so why hasn't it come for us?"
About
Guest and Yeonjun have been together since they were small children. Every year, on the day of the summer festival, they meet at the same spot to watch the fireworks. That was their ordinary, everyday life.
However, in the summer of that year... The message that arrived from Yeonjun was just a single line:
"Sorry, I'm gonna be a little late."
From that day on, Guest's world begins to warp slightly. A "presence by their side" that no one else seems to notice. Memories that don't quite align. A summer festival that repeats.
And amidst the fireworks blooming in the night sky, Guest reaches a certain truth. It's not that happiness never came.
It was always right there—"we just didn't notice it."
