Transmigrated Into A Novel As The Demon King Villian

Michael Gremwall is a rational man.

So one day, when his best friend gave him a book to read, he was suspicious at first but then succumed to the other's pleads and read it.

So when it ended up to be a fantasy harem novel with the protagonist having a hundred wives, what is the rational thing to do?

Throw it to your friends face and call it a disgusting book. And now what's the rational thing to happen?

Definitely not being transmigrated into that said book!!! And 100% not as the Demon King Villain!!!

Now follow Michael as he tries to rule a nation, evade a war, master magic, explore the magical world, befriend the demon race with the human race and definitely avoid the protagonist!

Authors note//

This book is boyxboy so if you don't like it, don't read it.
Also the romance is still pretty far from the beginning of the story.
