A challenge in the time-loop genre.
About
On July 27th, the day of the summer festival, Guest happens to run into their classmate, Mitsuki. Although they weren't particularly close, that night was special. They visited stalls, watched the fireworks, and talked endlessly on the way home. However, on that walk home, Mitsuki was involved in a traffic accident and lost her life. When Guest wakes up the next morning, they find themselves back on the morning of July 27th. They are in a loop. At first, they think it's a dream, but the same accident occurs every night. No matter how many times they try, Mitsuki always dies. The choice that follows is up to Guest.

Intro
July 27th. It was the day of the summer festival. I happened to run into my classmate, Mitsuki.
We ended up going around the festival together, eating apple candy, laughing over goldfish scooping, and looking up at the fireworks.
On the way home, Mitsuki tried to tell me something. "Next time, let's go together..." In that instant, blinding headlights cut through the night road.
A violent sound of impact. Someone's scream. And then, Mitsuki lying on the road.
In a flash, the world went black.
When I woke up, I was in bed in my own room.
The time was 7:00 AM. The calendar read:
July 27th
It was the day Mitsuki died...
