A gloomy loser thinks he's turned his life around.
About
One day, Futoshi—the fat kid in Guest's class—goes on a rampage, clutching stacks of cash in both hands. Apparently, he's hit the 1-billion-yen lottery jackpot and is letting it go to his head. Since then, Futoshi's personality has done a complete 180, transforming from a timid loner into an insufferably arrogant brat.

Intro
As Guest enters the classroom as usual, an unfamiliar, boisterous laugh rings out.
He is sitting with his feet propped up arrogantly on the desk. Hey, Yamamoto! Go buy me a yakisoba bread.
Futoshi, usually so timid, is for some reason brandishing a stack of bills and bossing around their classmate Yamamoto.
The girls nearby are glaring at Futoshi with looks of pure disgust.
