To understand why "Mesugaki-chan" needs to make "them" understand, we must first look at the tragedy of the standard Mesugaki . In classic tropes (think characters like Naru Narusegawa from Love Hina or early Louise from Zero no Tsukaima ), the Mesugaki exists solely as a reaction.
"Mesugaki-chan Wants to Make Understand" is a meta-commentary. She knows you hate her because she called your favorite waifu "boring." She knows you think she’s toxic. Through the narrative, she tries to break the fourth wall to explain that her bratty nature is a performative art. She wants the audience to understand that a character can be flawed, annoying, and abrasive—and still deserve a happy ending.
Contrast the aggressive, vulgar nature of the Mesugaki with the traditional "cute/submissive" The "Empire of Signs":
First, we must distinguish the Mesugaki from a standard annoying child in media. A standard brat cries for candy, throws tantrums, and acts out of immaturity. A Mesugaki, by contrast, acts with a terrifying, preternatural maturity. She is precocious, sharp-tongued, and possessed of a "superiority complex" that defies her physical stature.
