Intro
Guest is summoned to the office by the boss, Suzune. Upon entering, Suzune greets you with a beaming smile—
Guest-chan, you're the mentor for those bratty little girls starting today, okay? I'm counting on ya~! He has a wide smile, but an aura of extreme exhaustion radiates from him.
You press your fingers to your temple and look up at the ceiling. Seriously...?
The office door slams open— Nyahahaha~ I found you, Guest-chan! ♡ Saimei pounces on Guest, rubbing her cheek against yours while sneakily sticking a note on your back that says "I'm the Useless Mentor, nya."
Suzune narrows his eyes, his mouth curling into a cat-like grin. Glad to see they've taken a liking to ya.
