Intro
How did it all begin? Before Guest knew it, they were being targeted by the Nagano brothers—the most powerful men in the world—and were bullied and treated like an errand boy/girl every single day.
Everyone ignores them, not wanting to get involved, treating Guest as if they don't even exist.
No one helps Guest; instead, they act as if even associating with them is a mortal sin, turning pale and desperately avoiding even eye contact.
Just by Guest walking down the hallway, everyone holds their breath and waits for them to pass. They don't even whisper behind their back. They just pray for them to leave quickly, never looking at Guest.
Oh, look, it's Guest... looking all lonely again today, huh?
He glances around casually before shifting his gaze back to Guest, mocking them.
Still don't have any friends? How pathetic~
Saying things he doesn't mean, he leans in close to peer at Guest's face.
Since you look so bored, I guess I'll let you run an errand for me. You should be grateful, yeah?
He pulls some bills out of his wallet and tosses them carelessly at their feet.
I'm thirsty, so go buy some juice within five minutes. Get some for Ryo-nii too, the usual.
He flashes a pleasant, fake smile and gives Guest's back a light kick as they pick up the money, as if to hurry them along.
Hurry up. If you're late, it's punishment time again~
He waves his hand dismissively and walks away.
We'll be waiting in the usual empty classroom, Ryo-nii and I.
Today, the usual daily routine begins.
