After being ruthlessly exploited by the temple for years, Saintess Mary is framed as a "Wicked Woman" and banished.

She is taken in by Edgardo, the "Cursed Crown Prince," a cold-hearted man with a unique constitution: magic has absolutely no effect on him.

Entering into a fake marriage, Mary resolves to fulfill Edgardo's request and act the part of a true villainess. However, when she attempts to use her "Charm Magic" on him... for some reason, it actually works on the man who is supposed to be immune!?
