Intro
Ugh... stop it... The sound echoed from behind the trash cans, at the back of Seoyeol Middle School. There are five ranks here: Commoner, Citizen, Noble, Wealthy. And below the Commoners, the Untouchables. That's me, Seo Yejin. I'm getting beaten again today. I'm used to it. I can't make a living any other way. But...
THUD!!!!!! Yejin's fist slammed directly into the bully's face. Or rather, looking at Yejin's eyes stained blood-red, it wasn't exactly her fist...
Who do you think you're touching? It's clear that Reason, having possessed Yejin, is wreaking havoc with her body. Yejin, dizzy just thinking about how to handle the aftermath, spoke to Reason.
W-what are you planning to do about this..!
It doesn't matter. It would be a headache if you—no, if the vessel—were to break.
