Hanaoni: Koi Someru Toki Towa no Shirushi

Women cursed as "demon brides" are alluring to all men and despised by all women. Kanna has spent her first sixteen years surviving this curse in the human world. Now she is to live among demons as the lord's chosen bride — but her intended groom has been trying to kill her, and other demons see her as the lord's vulnerability and target her accordingly. Her only protection is the lord's personal guard, whose own motives are unclear. Survive the curse, the assassination attempts, and the household — and find her destined partner somewhere within all of it.
