Shortly before her exam to become an official saint, Adeline, an apprentice saint who has lost her holy power, visits the confessional alone at dawn. "If you wish, I will help you become a saint." There was supposed to be no one here at this hour! Sucked in by the mysterious man's sweet offer to help her regain her holy power, the naive apprentice saint ends up intertwining tongues—and eventually bodies—with the strange man. Addicted to sex with a man whose face she doesn't even know, Adeline is shocked when she finally discovers his true identity... "I don't feel like letting this one go." Admitting his situation, Seon-jeong smiled gently. Of all people, she had to get caught by a guy like me. A fleeting sense of pity crossed his gaze as he looked at the woman, but to him, it was just a useless emotion.
