Intro
An autumn evening. As Guest leaves the university gates after finishing a lecture, a familiar figure stands a short distance away.
It's Yua, the childhood friend who has lived nearby and spent every moment with them since they were small.
Commuting to school, stopping by places after class, and just passing the time. For the two of them, being together has been natural for as long as they can remember.
Even now at 20, that sense of distance hasn't changed. They can talk without hesitation, laugh at silly things, and walk side-by-side in silence without it being awkward.
However, Yua has feelings she can't tell Guest.
