After Becoming the Demon King, I Was Mistaken for a Big Shot's Widow

I'm planning to reopen the Hozuki arc as a new short-to-medium-length alternate timeline: "Even After Gaining Immortality, I Still Went to Hell." Next story: The Chess God's Legacy Upcoming stories: "He's a Dragon," a story about the Heavenly Restriction Tyrant and his dragon, featuring a quiet, desireless dragon boy and a carnivorous man. "Bad Seed," about the tragic original-character and a big shot who are at odds despite putting on a united front. Both are waiting their turn. Forty percent anti-piracy warning. This story is very out of character, so think before diving in! The protagonist is a cross-dressing male. He's a gorgeous, charismatic heartbreaker who gets away with anything. Canon couples may be broken up, though probably not. The protagonist transmigrated and lost his memories after transmigrating (important), so he's very out of character. Read with caution. There's no secondary couple. The protagonist is weak early on and gets stronger later, but he's not the world-destroying type. P.S. The protagonist doesn't seem very smart QWQ, so readers who like capable characters should be wary. He transmigrates as the human version of the legendary Demon King... and loses his memories. At last, he's escaped his sickly body and become a demon, only to find that every enemy is stronger than the last! On one side is the future Spirit King, with a million units of spiritual power; on another is the famous Abe no Seimei. Great demons roam everywhere, and there's the King of Curses too. Turns out I'm the weakest one here... So he figures out how to stay alive: wear the prettiest dresses and be the most shamelessly cautious demon. But why does everyone think I'm the widow of some dead big shot?! Broaden your horizons! You don't have to be a woman to wear women's clothes. [You don't have to be a woman to be a big shot's widow, either.] "That's such a broad-minded idea I can't argue with it... But why are all the big shots you keep talking about different people?" [Because you're a playboy who flirts with everyone.] "I'm not! I didn't! Don't make things up! You're all reading too much into it!" The concubine of an onmyoji? "I was undercover, that's all." At last, he reaches the modern era and finds the reincarnation of the onmyoji in Izumo. Everyone thinks he's deeply in love with that onmyoji. "I just have a wish I want him to grant." In Tokyo, he meets the reincarnation of the King of Curses, and rumors say she was his only wife. "A scumbag like him, with a wife?" Rumor has it he's the lover of Yokohama's former mafia boss. "I was new in town and trying to scam some inheritance money." The untold story of a mafia big shot's mistress and a pure-hearted high school tennis boy. [The unspeakable past between me and a dead big shot] Enough with spreading this gossip from person to person!! Today, I'm setting the record straight! It's all rumors. . The pairing is set: Xia Han. All the big shots: He can't live without me. "There's no need to think you're quite that important..." Have you ever, even for just a moment, loved someone? "..." "Yes." Theme: Don't believe rumors
