Lua, a candidate saint with healing powers. However, her abilities were flawed, and she would be pained and painful to herself in order to transfer the symptoms to herself and heal them. The saintly candidates treated her as a flaw, but only her best friend Ariane was always there. One day, Garrot, the Knight Commander whom Lua cares about, is dying. After completely healing his wounds, Lua wanders between life and death at the limit of her abilities. However, when she awoke, all the credit belonged to Ariane, and Garrot and Ariane’s engagement had been decided. Seeing Ariane’s true nature, she is coldly beaten by Garrot. In despair, Lua vowed not to heal anyone anymore. Then the Second Prince Swen asks, “Why don’t you take revenge on those who have demeaned you?” She uses another ability she has been hiding – the atrocious ability to inflict healing symptoms on others – and joins forces with Swen to start a new life as an “evil woman” instead of a “saint.”
