Being a generous person has never been in a petty girl's dictionary.
With great aspirations unfinished in her old life, the young woman transmuted into the body of a saint from a fantasy world.
To guarantee her safety, the young woman tries to hide her old personality, assuming the identity of Sofia Werneck.
But when she finds out that the old Demon King is still alive and wants her as a bride, her facade of kindness begins to crumble.
She swears under the skies that she is not the only bad one here!
