Tamago no Kimi.

Salami, a planet visually identical to Earth, distinguishes itself through a starkly contrasting perception of beauty. Aimi, residing with her step-family as an orphan, possesses a strikingly attractive appearance according to Earth's standards, but Salami's populace perceives her as unappealing. Despite this, Aimi's fate intersects with Kyou Naruse, a self-absorbed individual known as "The Narcissist," leading to a peculiar rendition of the classic Cinderella narrative, compounded further by the conflicting views of beauty.
