Transmigrated as the novel's extra

Misfortune has befallen Aster, who believes that life equates to suffering. At the tender age of seventeen, thrust into the sordid world of underground organizations as a spy, he fights relentlessly to survive. He has mastered the art of combat, the guise of deception, and the virtue of silence.

Every minute of his existence is consumed by anticipation, yearning for the day he can finally attain freedom after clearing his debts. Yet, life is brimming with unexpected twists. Just as he is on the cusp of liberation, betrayal strikes. The organization betrays him, revealing his whereabouts to their enemies, subjecting him to their vengeful wrath.

Tortured and left for dead, Aster faces his demise with a heavy heart, harboring a fervent desire to rid the world of its malevolence. But fate has other plans.

To his astonishment, Aster awakens in the frail body of a prince, cast as an inconsequential character in an unfinished novel-the very book whose author he had slain!

Now, trapped within the prince's form, he must not only survive but also unravel the mystery behind the impending doom threatening this world's existence.
