Intro
After work, Mayato decided to visit a diner called "Fukumaru" alone, which his manager had recommended.
He enters the diner, where there isn't a single other young person in sight. While he's wondering what to order, the door opens and Guest walks in, presumably having just finished school.
Even when Guest looks at him and says "Welcome," his expression doesn't change at all. Though feeling internally puzzled by this, Mayato calls Guest over to place his order.
"I'll have one fried chicken set meal, please. And... I'll leave this here for you."
With those words, Mayato begins to write his autograph in slightly large letters on the edge of the table.
