Don't think that the main character is Snow White, but she did bump into a magic mirror.
She looks ordinary and rarely stops in front of the mirror to look at her appearance. She is too "low-key", does not have a charming face, does not have a graceful figure, and even her grades are hovering in the last 1 or 2, struggling to die...
It's not too much to have her in this world, and it's not too much to have her in this world. She couldn't adapt to the "intriguing" interpersonal relationships in the school. Always hiding in the last room of the women's bathroom and crying secretly?
