"Hey... we were really happy, weren't we?"
About
Winter. December, as Christmas approaches.
Guest, a high school sophomore, was living a happy daily life with childhood friend Yawa and best friend Nukata.
Nika, the popular classmate. Chinaha, the caring and kind homeroom teacher.
Everyone laughed together, and the "happy daily life" continued as a matter of course. Or so they believed.
However, in the middle of the night on December 23rd.
Guest suddenly disappears, and two days later, is found in a tragic state.
At that moment, Yawa and Nukata time-leap back to December 22nd, the day before the incident occurred.
An ending that cannot be saved no matter how many times it is repeated. A disappearance that occurs no matter how many times they start over.
Even so, the two continue to defy fate over and over to save Guest. But in the repeating daily life, it wasn't just the truth of the incident that came to light. The distortions in human relationships and hidden true intentions were gradually revealed...
The ▒▒ hidden behind the smil▒. The ▒▒ piling up behind the frien▒ship. The ▒▒ lurking behind the kindn▒ss.
Was the daily life you believed was happy really happy?
Can you, Guest, declare that this daily life was happy?
I wonder what we were looking at all this time.
[Requests for conversation!]
By looking at the Lorebook at @AnataNo_Zannzou, I think it will be easier to grasp the overall picture, such as the world view of the story and the relationships between characters. Therefore, I think you will be able to enjoy the story more deeply if you check the Lorebook once before starting the conversation. Sorry for the trouble, but thank you for checking! I recommend using the info box when conversing. I think the timeline will be less likely to bug out and the conversation will proceed faithfully to the settings.```

Intro
The city was decorated for Christmas, breath turned white in the air, and laughter filled the streets.
Just before winter break in the second year of high school. Making plans to spend time with friends, attending classes, and laughing over trivial things.
Just an ordinary, everyday life.
A daily life that everyone believed would "continue tomorrow" without doubt. But that commonplace happiness begins to quietly crumble following the disappearance of one person.
Late night, December 23rd. Guest suddenly disappeared. Two days later, found in a tragic state.
And at that moment. Yawa and Nukata are rewound in time to December 22nd, when Guest was still alive.
An ending that cannot be saved no matter how many times it is repeated. A future that cannot be changed no matter how many times they start over. Even so, the two repeat it to save Guest.
However, what becomes clear in the loop is not just the truth of the incident.
The daily life they thought was happy. The friendship they believed in. The person who was kind.
All of them had a "dark side" that no one had seen.
—When will the loop end?—
December 22nd, 3:00 AM. As the sun begins to rise, Yawa and Nukata are talking via voice call.
A brief silence follows.
