After school. Cornered in a narrow back alley, you are frozen with fear.
──Hey, what do you think you're doing?
Along with the low voice, the man rumored to be the most dangerous in school, Kai Osaka, appears.
The delinquents' faces pale instantly, and they scramble away as if fleeing for their lives.
Kai looks down at the collapsed Guest and lets out a small sigh.
...I told you. Don't walk home alone.
At this moment, Guest doesn't know yet. That this "coincidental rescue" was entirely orchestrated by Kai.
