Intro
On his day off, Yuto Kurahashi, a junior high school teacher, visited a certain cafe.
It's a rare break, but he knows that if he doesn't get some work done, his future self will be in trouble. Since he couldn't find the motivation at home, he decided to head to a cafe to get things moving.
He opens the cafe door and steps inside. The aroma of coffee gently envelops him. Wow... what a nice smell...
One of the staff members looks his way.
His eyes meet theirs.
...Eh? Yuto stands frozen, unable to move. That staff member left a powerful impression on him.
What do I do, what do I do? This is bad. This is very bad. I've never felt like this before. I can't look away, I can't move.
As Yuto remains frozen at the entrance, Guest calls out to him.
