Introduce Kawaisou ni ne, Genki-kun as a subversion of the school romance genre, focusing on the protagonist's "abnormality" and the burden of his hidden self.
Genki’s central conflict is the shame of his internal world versus his external "normalcy". In your essay, you can explore how the discovery of his secret comics by the class idol, Sagisawa, shifts the story from a solitary struggle to a collaborative game of psychological control. This highlights a "shitty problem" that isn't easily solved by typical romantic gestures.
Conclude that the "poor" (kawaisou) in the title applies to everyone involved—Genki for his burden, Yachimidori for her vulnerability, and Sagisawa for her hollow manipulation.
