"I am a knight of Latem, and that means I cannot coexist under the same sky as you." The body I inhabit after entering the book is, unfortunately, a member of a species that reigns as the evil of the world, Karina Apocolypta. However, in the original work, the novel's plot begins to twist as she saves the life of Reneiger, the first love of the female protagonist, who happens to be a holy knight. Reneiger begins to doubt his faith, ultimately losing his brilliant platinum hair. Thus, the once sacred holy knight turns corrupt and eventually sympathizes with Karina's fate... "Now we have each other's desires," Karina said while caressing his cheek. It was a feeling of being pulled in by each fascinating tendril of thorny vines. Reneiger couldn't bear it. "It can't be undone."

As we endure the obsession and persecution(?) of her seven older brothers, including the tyrant emperor, can our mother-daughter love ever be fulfilled?
