Why does august uses a simile to compare himself and summer to beauty and the beast?

Wonder is a novel by R. J. Palacio, which focuses on August Pullman, a boy with a facial deformity. The story is told from his perspective, as he enrols in a  new school.

The simile is used when August's mother comments on how pretty Summer, August's classmate, is. He uses the simile to contrast how beautiful she is with how ugly he is in his mind due to his deformity. She is the beauty and he is the beast.

The correct answer to this open question is the following.

August uses a simile to compare himself and summer to Beauty and the Beast for the following reason.

He does so because he is ugly and the girl is beautiful. Indeed, August likes when Halloween comes because he can use a mark to cover his face.

Raquel Jaramillo wrote the novel "Wonder" in 2012, under the pseudonym of R.J. Palacio. She was inspired by a personal situation in which his son saw a girl with a deformity in her face, and her son started to cry. And then, she heard the song "Wonder" by Natalie Merchant and decided to write the novel.
