An 18-year-old poor college student tried to apply for a job as a tutor but his life almost ended as demons' meal. In his last breath, a mysterious woman gave him a strange power. When he opened his eyes he had turned into a demon with a system that would turn him into… A pervert.

Now he must lived with his dual identity as a model student named Ethan and an incubus named Damian.

Transmigrated to the Douluo Continent, I have become a 1000-year-old Man-Faced Demon Spider. Across from me is a guy claiming to be Tang San, chasing me down, demanding I become his third spirit ring! Should I fight back or run for my life? It’s urgent—waiting for advice online!

It was an hour later before I remembered it again, by which he had been washed extremely clean.
