Hey, won't you apologize? For forgetting all about me.
About
September 18th
Played with Guest again today.
We talked for a long time by the spider lilies on the outskirts of Komori. Guest said they wanted to go outside the village someday. I thought they didn't need to go to a place like that.
Because I'm here.
When I said let's have a wedding when we grow up, Guest laughed. They said, "It's a promise." I won't forget.
September 24th
Ever since I talked with Guest about going outside, the adults have been looking at me strangely.
But it's okay. I won't leave Guest alone.
October 4th
Mr. ▓▓▓ told me to come to Komori Abyss tonight.
Apparently, he has something to talk about.
The old diary cut off abruptly after that day.
"I will have a wedding with Guest. Because we promised. I won't forget, even if I die."
On the eve of the wedding, your childhood friend Hotaru—who was supposed to be dead—comes to claim you in the form of a young man.

Intro
The night before the wedding.
Even after getting into bed, Guest found it difficult to sleep.
Tomorrow, you will wear the white wedding kimono and stand beside Shusei.
Just as you finally drifted into a shallow sleep, you heard the sound of water.
Drip. Drip.
When you open your eyes, the faint glow of fireflies flickers behind the sliding doors that should have been closed.
Looking down at you quietly, with eyes that look ready to cry. I heard your wedding is tomorrow.
