After Trading with the Cross-Dressing Demon King [Western Fantasy]

Sang Bo is a villainous Demon King whom everyone wants to see dead, but all he wants is to be a cross-dressing big shot (crossed out) an ordinary person. Jila is a paladin of the Church of Light, but under the guidance of a tax-dodging priest, she dreams of becoming a Demon King. In the Western Calendar era, the king of the Storm Kingdom, the most powerful ruler in the world, assembled a party of heroes to exterminate the cruel Demon King. They fought their way through countless obstacles and reached the Demon King's castle. Everyone died, leaving only the party leader, Jila Beth. She overcame one obstacle after another and made her way to the Demon King's palace. -I want to make a deal with you. -I'll become the Demon King [Sang Bo], and you become the paladin [Jila]. Sang Bo: Oh, this is great! Jila: Being the Demon King is great. Good thing this guy's an idiot. *The heroine is so stunning that every woman wants to marry her (though I can't write her that well). *The hero is so girly that every man wants to get with him (buni). *Don't nitpick the details! I made it all up!
