The Sin of the End: The Delightful Life of the Wicked Demon King

The deeper the love, the more painful the hurt!

After the world hurt me, I fell into darkness and became a demon, even going so far as to destroy the world.

I thought I could endure the loneliness and stop caring.

But when I felt their love, I couldn't help responding to it.

World, you really are despicable. Are you trying to make me give up destroying you by using them?

A queen, a princess, an elf, a witch...

Tch, begging for mercy because you can't win?

At least you know what's good for you.
