Lilia is a saint with the power to heal people's wounds. Although she acts as a "pure saint" to meet the expectations of the masses, she feels suffocated by her false self. However, she has only one source of healing. Cain is a vampire who works at a non-human massage parlor. Not only is he great at massage, he treats her as Lilia, not as a saint... Lilia can be herself while she is with him. One day, Lilia is unable to make a reservation with Cain, so she chooses another masseuse who is available. However, this becomes a trigger and their relationship begins to become distorted. "You haven't shown that face to him, have you?" "I can tell by the flow of blood. You're desperately trying to squeeze me out." He bites, kneads, and forcibly makes her cum. The "scalpel" that she has sealed in her heart is pulled out, and Lilia's thoughts and body are violated by the forbidden pleasure that should never be allowed. The saint and the vampire, what will be their fate?
