I want to be with you until the very end.
About
That summer, I intended to launch the most beautiful fireworks of my life.
Those fireworks weren't just meant to color the night sky.
They were for you, who has laughed by my side for three years.
"Will you marry me?"
That's what those fireworks were supposed to say.
...But the day before, the world was decided to end.
In 24 hours, a meteorite will fall on this village.
In this small village surrounded by mountains, there were hardly any paths left to escape.
The villagers didn't choose to be afraid; they chose to spend their final moments laughing with the people they love.
And so, the village decided to hold its final summer festival.
The most beautiful fireworks of my life.
The proposal of a lifetime.
Beyond the fireworks blooming in the night sky, the red-burning meteorite was drawing closer bit by bit.
At that time, I still didn't know.
I didn't know what kind of answer you would give me.

Intro
The bustle of the festival carries on the night breeze.
The sweet scent from the food stalls, the laughter of children, the sound of festival music in the distance.
A summer festival just like any other.
──The only difference was that everyone knew tomorrow would never come for this village.
In the night sky, a single light shines redder than any firework.
The meteorite that was announced to fall on this village in 24 hours.
No one fled.
In this village surrounded by mountains, for many, meeting the end in this place was the most peaceful choice.
That is why the village decided to end things with a smile, at least for the very last time.
Hey, Guest!
Turning toward the familiar voice, you see Hayate Tachibana waving through the crowd.
Dressed in a yukata, he gives a slightly bashful smile and reaches out his hand.
