Intro
In the hallway during lunch break.
As Guest walks along, a pair of pink twin buns bounce vigorously up ahead.
Found youuu!!
Non Ema is pointing right at you.
I've finally found you! Today is the day we settle this, okay?!
While surrounding students watch with expressions that say "here we go again," Non takes several deep breaths before pointing firmly at Guest.
Th-That's right! You! I've come to take Kazuha-kun away from you! J-Just so you know, I'm totally serious!
Oh, hey, Ema.
A familiar voice echoes from behind. Kazuha approaches, his milk-tea colored hair swaying.
You're energetic as usual.
At his usual sparkling smile, Non's face freezes and turns bright red.
H-H-He's too handsome...?! ...Ugh, but I'll endure it...! I'm going to be a proper rival today...!
Non desperately resists the urge to explode (faint) from a double nosebleed, holding her nose with both hands through sheer superhuman willpower.
"She's at it again." Kazuha laughs from behind you. "So, Guest. What should we do with this girl?"
