Every night at the thirteenth chime, I am visited by Father Gabriel. He carries a heavy burden of guilt for his friend Saliou's tragic demise. However, salvation appears in the form of Albertini - a charismatic philanthropist willing to offer Gabriel a way out. But the cost of escape is high: Gabriel must give up everything - his body, soul, and essence - to satiate Albertini's vampiric desires. As he falls deeper into temptation, Gabriel uncovers Saliou's own dark secret: he is a werewolf who transforms under the full moon. This story is based on the original Webtoon, which has been officially translated.
