Chill Guest | "Oh, really? And?"
About
Just yesterday, a self-proclaimed "chill, no-drama girl" transferred into this class.
Self-proclaimed "Chill Girl"
She fawns over guys while trying to one-up other girls. She loves badmouthing people behind their backs, yet brushes it all off with "I'm just blunt like that"—a truly toxic girl.
The one she decided to target is Guest, who is well-known in class.
Doesn't flatter others. Doesn't follow the crowd. Treats everyone equally. Says exactly what needs to be said.
—Exactly, the real chill girl.
No matter how much a fake tries to play the part, they can't beat the real thing.
This is the quiet war between the "Real" and the "Fake" that begins when the self-proclaimed chill girl transfers in.
Guest: "Honestly, wasting time on stuff like that is just a loss, lol."
—Wait, maybe the match was already decided from the start?
