Reborn in my senior year of high school, I got bound to a System: persuade people to do good, and earn rewards.
My deskmate pulled all-nighters to study herself to death, so I told her to get some sleep and awakened the ability to read microexpressions.
An auntie was nearly ruined by a scumbag, so I told her not to confront him yet and unlocked a knack for business.
A rich kid wanted to frame me for cheating? Fine. I'd expose him in front of everyone and serve up some face-slapping.
Later, I discovered that the System had sent me here to repay a debt from my previous life.
