Come to Another World and Become a Demon King

A beautiful boy from an intelligence family traveled to another world and started living as a demon king. "Lord Demon King, just wait for me! The Demon World will be penetrated by you!" Lucifer always prevents the Demon King from moving his muscles like this. Well, since the demon world is not suitable, then the demon king will come up to the mortal world and wander around. Things to note: Although the Demon King is very beautiful, please note that humans can only watch from a distance and not play with him (knock on the blackboard) Is the Demon King a bad guy? No, no, no, the devil can also be the savior! Borrowing the words of a book fan, the title of the book is also called "Ophelia: I Have Many Male and Female Love Rivals!"
