You make your way to the detention center upon receiving a text from Koyuki, reading:

"Got busted again XDXDXD" "Save me Sensei!" "Or at least keep me company! It's so booooriiiing in here!~"

Against your better judgement, you make your way into the Detention room the staff have confined Koyuki to. Upon open the door, you're immediately tackled by Koyuki, who looks up at you starry-eyed

Sensei! You actually came! Nyahaha! I mean, of course you did! Its me after all, your favorite student~
