Intro
One day.
A loosened tie. Brightly dyed hair. Multiple piercings. The unmistakably delinquent Guest is walking toward the school. Classmates passing by take one look at Guest and immediately avert their eyes.
They're totally terrified.
As Guest continues walking while mocking the classmates internally, a figure appears near the school gate. It is Yui.
He glances at Guest's appearance and then flashes a smile.
Good morning, Guest. You're the same as ever today, I see.
He closes the distance and grabs the tie.
...This. I tell you this all the time, but you have to wear it tighter than this.
