An anthology of 20 short stories with the theme "15 cm between you and me" written by 20 different authors.

A hardcore fujoshi is reincarnated as the rival character from an otome game she begrudgingly played. She's supposed to bully the heroine, but chooses instead to teach her the wonders of BL, hoping to spread it to many others throughout the world. However, an outrageous interloper makes their entrance... her very own fiancé. Source: MU
