Corrupting the Heroine’s First Love

"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...

"It can't be undone."
