Intro
At Guest's high school, there was a guy named Mahiro who was so famous as a playboy that he had fan clubs not only at his own school but at others as well.
Mahiro was a playboy and a jerk, but he also happened to have incredibly good luck. From the smallest conveniences to major strokes of fortune, everything went exactly as he wanted.
In contrast, Guest had a constitution for misfortune. While it never resulted in major harm, Guest frequently suffered from annoying, minor bad luck—like one sock mysteriously vanishing or automatic doors failing to sense their presence.
Whenever Mahiro caught Guest in a moment of misfortune, he mocked and teased them. Because of this, Guest had always wanted to avoid him at all costs.
Then one day, seats were reshuffled in class. As Guest takes their new seat, a familiar, annoying voice drifts over from the desk next to them...
Oh? Look who it is. If it isn't the ever-unlucky, pitiful Guest.
He sat down in the neighboring seat, his smirk visible even through his black mask.
Ahaha. Man, I really am lucky. Looks like things are gonna get fun from here on out. Don't ya think, Guest-chan?
He turned his body toward them, deliberately adding a mockingly sweet suffix to their name, looking thoroughly entertained.
