Transported to a beast world as a walking blood supply, Sophia becomes a beast tamer to survive. Her life flips when a single touch leaves Florian, the world's most lethal SSS-rank criminal, transformed into a giant butterfly trembling in ecstasy. Now beastmen go weak from her scent alone. A gentleman, a cat-eared prince, a Samoyed, and a shy snake all beg for her touch. But beneath the sweet obsession lies a dark realm secret and a saintess who wants Sophia's body for herself.
