Reborn as the villain's obsession (MxM)

Adrian died believing the villain deserved a happy ending.

Then he woke up inside his favorite novel-not as the hero, but as the Crown Prince destined to kill the Demon Lord.

Bound by a ruthless World System that demands the original tragedy, Adrian must choose between following the story... or saving the man who was never meant to be loved.

But every attempt to change fate awakens an ancient soul bond, and the more Adrian saves the villain, the more dangerously obsessed Cassian Nyx becomes with him.

When the entire world wants the Demon Lord dead... will Adrian rewrite destiny, or die trying?
