I Was Raised by a White Knight Who Pretends to Be Upright but Is a Bloodthirsty Killer

(A cold, expressionless, ruthless male lead X an insecure, overlooked girl who transforms)

They start out with a life-and-death connection: the heroine's male body died at the male lead's hands.

Hugh, a white knight cursed to be unable to see the faces of the living, killed the noble Carme while destroying an evil ritual. At that moment, he discovered that he could see the face of the girl at the ritual's center. Meanwhile, Carme, who had been killed, was reborn in the body of the ritual girl who was supposed to be a sacrifice...

Hugh: "Stella, come here."

Stella silently hid in a corner.

Hugh drew his sword. Before the enemy could even say a word, Stella surrendered first.

Hugh, thinking: Why are the people I save more afraid of me than the people I kill?

Stella, thinking: Why do I have to call the person who killed me my benefactor?

A twisted romance between Hugh, who can only see Carme's face, and Carme, who was killed by Hugh.

The ritual girl is actually a princess of a fallen kingdom, and her true identity draws them both into a plot to destroy the world.

A white knight and a transformed villainous young master save each other. One hides his coldness behind a sunny facade, while the other buries the past and turns over a new leaf.

A cold, ruthless knight with terrible people skills X a reformed, transformed villainous young master. A heavily altered DND setting.

Not sure whether "pure love" here means BL, as on JJ. This is a one-on-one boy-girl romance.

Warm and funny at first, tangled and angsty in the middle, with a happy ending.
