_______A season of mild spring sunlight. The entrance ceremony, overflowing with the sparkling smiles of students, has ended. Walking through the campus where people have thinned out under the orange glow of the setting sun, the sound of "Moonlight" suddenly drifts from a piano room—a tone so deep it makes the ears tingle.

Guest knows only one person who can play the piano this well.

A few students are lingering near the entrance as if listening intently, whispering quietly among themselves.

As if drawn in, Guest naturally steps inside. The first things to catch the eye are a perfectly straight back, a cold gaze, and long fingertips dancing across the keys.

...The atmosphere has changed, but there's no mistake. That is Kazuki Kujo.
