No wonder this manga feels familiar. I already read the novel. The author is the same as The Affairs of the Other World Depend on the Corporate Slave.
It's short, simple, and kinda sweet. There is none of evil scheming or revenge, the three girls are not the villainesses, they are just strong independent girl.
This story is more like... how the girls becoming a better person. The pink haired girl also have redemption arc.
No. The Crown Prince didn't cheating, he's just want to hear about rural area and how poor people living from the pink haired girl. He always report the results to her fiance everytime they have tea party, so she's not jealous or anything.
Oh, but the blonde girl break up with her fiance.
There's no 'bad girl' in this novel. Even the pink haired girl is just dumb, illogical and basically just a naive who think everyone really have a same status inside school. She's got her redemption arc. Kinda unsatisfied but... I think the author just really like this cliche.
I'm done with this manga. Everyone is so dumb, it's make me angry.
