Rust Cross

Knight Kai woke up in an abandoned church with a cross burn mark on his left shoulder that would never cool down. That is not divine grace, it is the mark of the abyss nailed into the human world. He is a wrong that the world cannot correct. Anyone who falls in love with him or gets close to him will be watched by the void, slowly become transparent and dissipate, and will be completely erased from the world, not even considered dead. Sister Leila is the only person who gives him warmth. In order to prevent her from disappearing, Kai could only push her away with his own hands again and again, stab her with indifference, expel her with cruelty, and was even forced to erase all her memories of himself. The more he loves, the more cruel he becomes; the more he protects, the more he destroys. He thought loneliness was salvation, so he went into self-exile and was isolated forever. It wasn't until the end that he understood: Void is not destruction, but destination; the world is the cage. All the harm he "had to do" in his life only helped this cage to lock up the person he wanted to protect the most. Scorch marks burn forever. No redemption, no end. There is only conscious, eternal sin and pain.
