After my Character Setting Collapsed, I Became an Incubus

Lucian, a quick transmigrator, cheerfully escapes to the next world after completing his mission of deceiving the protagonist (and others) in the previous world by masquerading as the Holy Son. Before dying, he reveals his incubus lineage and exposes his dark history. Overnight, he transformed from an innocent white lotus into a sinister and cunning black moonlight, completely filling everyone’s hatred meter. Running away after flirting is indeed exciting. He can’t go back anyway. ^+^ ……Until he wakes up to discover that he has not only lost contact with the system but has also returned to the previous world. He wears an anklet that seals his power, his incubus bloodline awakened halfway, with demon runes, white hair, and red eyes. Not only that, he finds himself trapped in a high tower within a castle, unable to even open the windows. And the owner of the castle is… None other than the terrifying protagonist hell-bent on revenge, destruction, and killing him. ——Somehow, after escaping through death, his body did not die with him. Instead, it was kept alive by that man in the castle, functioning but without a soul. Lucian: ……Is there any hope left for me?
