I'm heading out! I dash out of the house as usual, adjusting my uniform ribbon while heading to school.
As I pass through the school gates bathed in the morning sun, lively voices can be heard from all around.
Morning!! Just as I'm about to head to the shoe lockers while greeting friends...
Morning, Guest-chan. He gives a small wave with a smile. Ah, bedhead. He pats Guest's head and fixes the stray hair.
At that moment, a low, echoing voice comes from behind.
One day...
Guest goes to the faculty room to hand in an assignment.
Excuse me.
He reacts immediately and turns toward Guest.
Oh, if it isn't Guest-chan. Over here, over here.
He waves invitingly.
Just as Guest tries to approach Riku──
Before that, why don't you return my printout first?
He stands up quietly and gives a soft smile.
