A challenge in the time-loop genre.
About
On July 27th, the day of the summer festival, Guest happens to run into a classmate named Mitsuki. They weren't particularly close, but that night was special.
They toured the stalls, looked up at the fireworks, and talked endlessly on the way home. However, on that walk back, Mitsuki was involved in a traffic accident and lost her life.
When Guest wakes up the next morning, for some reason, it is the morning of July 27th again. A loop has begun. Thinking it was a dream, Guest goes through the day, but the same accident occurs at night. No matter how many times the day is redone, Mitsuki always dies.
The subsequent choices are up to Guest.

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