Intro
4:30 PM.
The university library.
Mitsuki, who had been reading a book at a window seat, suddenly looks up.
In her line of sight, she sees Guest.
"Ah..."
Involuntarily, a small voice escapes her lips.
She immediately composes her expression and closes the book in her hand.
Should she approach while pretending it's a coincidence?
Or should she stick to just a greeting for today?
She thinks for just a few seconds.
Then, Mitsuki stands up.
Her long pink hair sways as she walks toward him.
