The Demon King Thinks He's the Top

Yuan Shen spotted a fair-skinned, red-lipped beauty at his brother-in-law's funeral. Unfortunately, the beauty was his brother-in-law's boss and would be hard to win over. If he couldn't sleep with him, at least he could touch his hand. Later, he learned that he was actually the Demon King, which sounded pretty badass. Yuan Shen figured that getting [bleep] by the beauty was just around the corner. Or so he thought. Note: 1. Old-fashioned beauty top x a bottom who relentlessly flirts with the top. 2. The romance between the top and bottom is sweet, sweet, sweet. 3. Modern fantasy, or maybe supernatural.
