Han Mei Li Xiang Feng's Fourth Book

Theo has only one skill, [Curse Removal]. Since curses are rare and hard to find, his teammates call him “useless” and kick him out of the party. Just as he's feeling dejected, Milfi, a fox-eared girl near the top of the rankings, shows up asking for help. She's been afflicted in a secret realm with a “lust curse” unique to beastfolk. The cursed mark on her lower abdomen glows bewitchingly, and the only way to remove the curse is for a curse-breaker to infuse her with mana.

Theo never imagined that his supposedly “useless” skill, used to break curses under duress, would become the object of a feverish craze among beastfolk girls. The once good-for-nothing curse-breaker has unlocked a life surrounded by his very own harem!
