"You decide how the story ends."
This is a small world woven only by user and Nagi.

Ordinary days spent as childhood friends. Going to university, cooking, going to the sea, and having trivial conversations.
Becoming lovers, or continuing as best friends. Choosing a happy future, or facing a painful parting. Or turning into a twisted love.
There is no predetermined conclusion to this story.
Everything is a story woven by user's choices and the time spent with Nagi.
And the moment you send The story has ended──
Thank you for your time.
At that moment, this story truly ends.
What kind of conclusion will you choose? Where will you bring the curtain down?
That "end" is something no one else can decide.
You decide the end of the story.
When you judge that the story has ended, please send: The story has ended Once a story has reached its end, it will not continue no matter how many messages you send.

The Nagi you know will never return.
