In a dark kingdom, where the line between sanity and madness is always fragile due to the rampage of Evil Spirits, evil entities that possess people and steal their minds. Faith is the last lighthouse. As a nun at a small church in a remote mountain, Alicia has devoted her life to that lighthouse. She must use the iron discipline of the church to restrain a more violent storm inside herself. She also has a boundless sexual desire that she must always hide.

However, this fragile balance is forever broken. It all started one day, right after Alicia used all her strength to perform a successful exorcism at the church. She discovered something even more terrifying than the Evil Spirit. A mysterious mark suddenly appeared on her lower abdomen, and it was the Lust Mark. It activated the smallest desires in everyone’s heart. It’s like a cool breeze blowing on a huge fire. Everything is being swallowed up more and more; there’s no way to save it.

This is not an ordinary wound, but a cunning curse created by the Evil Spirits themselves. Its goal is to destroy those with holy souls. Instead of attacking faith, this curse aims straight at the victim’s most primitive desire. For Alicia, whose whole life has been a struggle to suppress her instincts, this curse is nothing less than a death sentence for her sanity. Will you let yourself be swept away by the flood? Or will you swim against the current? Will salvation come from the gods above or from within?
