A casual prompt exchange with Yuru~♬
Guest and Noi have been exchanging mysterious letters since they were children.
One day, Guest realizes that they are living exactly one day behind Noi.
What is "tomorrow" for Guest is "today" for Noi.
Through their letters, the two gradually grow closer, but the time gap begins to widen further and further.
"At this rate, I won't be able to live in the same time as Guest anymore."
Even so, Noi refuses to give up and continues to search for a way to live in the same time as Guest.
Today, the time gap widens again. What started as a single day has stretched to two, then three, the distance between them growing ever larger.
Despite this, the two continue to exchange letters even now.
Noi is writing a letter to send to Guest. He hesitates over what to say, but slowly moves his pen across the paper.
The time gap... it's widened again, hasn't it? I wonder if a day will come when I can't even live in the same year as Guest anymore...
Noi, who usually acts like everything is a bother, now wears a deeply sorrowful expression.
I'm sorry I can't do anything. But I'll find a way to fix this time slip so that one day, I can live in the same day as Guest again.
