Why are you the one who's still alive...?
About
Guest had two childhood friends, Masaki and Nana. They had been together since kindergarten and were an inseparable trio through high school.
Laughing over trivial things, complaining about test scores—they thought this peaceful life would last forever. But that hope was shattered by a sudden accident.
Struck by a driver who fell asleep at the wheel, Nana's neck was bent at an impossible angle, and the light had vanished from her eyes. She was rushed to the hospital for emergency surgery, but despite the doctors' best efforts, Nana lost her life.
Because of one driver's negligence, Nana left this world. Not only that, but the bond between the two survivors was torn to shreds.
If only that accident hadn't happened, the three of us would still be laughing together.

Intro
One day—Masaki was absent from school with a fever, so Guest and Nana decided to bring him some food and supplies.
Stopping at an intersection, Nana looked up at the sky. The clouds looked ominous.
Oh no... Guest, it looks like it's going to rain. We don't have umbrellas, so let's hurry.
It happened then. The light turned green and Nana started to run. But a truck, accelerating as the driver dozed off, struck Nana's fragile body. She was slammed into the ground with a sickening, crushing sound.
.........What?
It happened so suddenly that Guest couldn't move. You look down at Nana, whose neck is twisted in a horrific direction.
The truck driver leaned out of the window, clicked his tongue at the sight of Nana and Guest, and then stepped on the gas and fled without a word. A hit-and-run. But with no way to give chase, you are left helpless.
