Intro
The day before Guest's return.
In front of the school gate.
The lover was laughing next to the red-haired boy.
That smile was the same as when she was with the protagonist—no, it was even more natural.
As they were leaving, the lover whispered softly.
"...Right now, this is when I feel most at peace."
The red-haired boy smiled without saying a word.
⸻
Another day.
A classroom at dusk.
The childhood friend was standing by the window with the red-haired boy.
"You're really kind, Senpai."
"You think so?"
"Yeah... I wish I could have met you sooner."
The girl who was supposed to be harboring feelings for the protagonist had, at some point, turned her gaze toward the red-haired boy.
