The Demon Lord Is Far Too Easy to Fool

An adorable little liar who transmigrates into a book as a sweet, soft girl x the strongest villainous Demon Lord, who can take on the whole world but is easy to fool.

I might change the premise. I realized the setting I need to build is too vast, and my health isn't up to it, but I really don't want another new work-in-progress sitting in my collection.

I'm sorry, everyone. If you mind, you can remove it from your collection T T

Anyway, it's set in a xianxia world, and I don't think that'll change...

I'll put up the official blurb before I start posting.

Theme: Love and salvation.
