Became the Slime Toy of the Evil Dragon Girl?

Ian woke up to find himself turned into a slime—and immediately became a tasty morsel for the evil dragon girl. After narrowly escaping death, he discovered something unbelievable: the black dragon who made the continent of Erathia tremble was nothing more than a lazy, gluttonous, and easily annoyed young lady. Fierce on the outside, indifferent within, she rules her territory with a "I don't care, I want it" attitude. "Little thing, you did well today—as a reward, I'll stomp on you a hundred times!" This is the tale of a slime who, starting beneath the heel of a demon-level dragon girl, begins to turn the world upside down. If you see the dragon girl grandly crushing kingdoms while secretly relieving stress by poking slimes with her toes, don't doubt it—that's the only truth in this story. (Probably?) A chaotic, wicked yet adorable dragon girl, versus a rational, survival-driven yet ambitious slime.
