“The final moment is approaching.
This is truly my last request… … .”

After the death of someone precious to me, I lived my life giving up everything.
In high school, he meets a girl who is hospitalized with 'luminous disease'.
The girl's name is Watarase Mamizu.
The 'luminous disease' she has causes her body to glow faintly when exposed to moonlight,
It is said that the closer death gets, the stronger the light becomes.

I ask Mamizu, who has a limited lifespan, what she wants to do before she dies and make suggestions.
“Can I help you with that?”
"really?"
With that promise, my time, which had stopped, begins to move again.

The best love story I want to tell to everyone living in this moment.
