The Demon King I Have to Win Over Is Actually Me

[Vampire Clan | Narcissistic Romance | Fake Paper Couple | Protective Top and Pampered Bottom | Romance-Focused]

CP: A proud, prickly human bottom who seems sweet but is secretly cunning x a possessive, obsessive, sly old fox of a vampire king top

Heiress-born young master Shen Xi went skydiving one day, only to travel body and soul to Blue Star in the year 2623, a parallel world where humans and vampires coexist.

As a newcomer, Shen Xi was forced to bind himself to the "Demon King Conquest System":

[Host's mission: Help the Demon King eliminate his rivals, prevent him from turning evil, increase his favorability, and win him over and heal him...]

Shen Xi could only think that this was absurd. What did it have to do with him?

In an instant, the Demon King, who had endured a thousand years of schemes and murderous intent, abducted him to his manor and pushed him down onto the bed, pressing his nose against Shen Xi's warm Adam's apple.

His red eyes were sinister. "Can you smell it? We have a very similar scent."

Shen Xi's mouth twitched. "..."

When he saw that the other man's face was almost identical to his own, his pupils shook with shock. The Demon King was actually me?

Not long afterward, Shen Xi acquired the art of soul manipulation and discovered that he and the Demon King shared the same soul. Through it, he glimpsed the Demon King's innermost thoughts and tragic past.

He plotted in secret: Maybe... I should help this poor version of myself?

So, in the days that followed, Shen Xi dealt with the Demon King's deep suspicions and control, as well as his many tricks and fits of madness.

At the same time, he focused on completing the System's missions, hoping to return home as soon as possible and not daring to slack off for even a moment.

At last, he helped the Demon King reclaim what he had once lost. But then the Demon King kept him firmly at his side. Shen Xi couldn't escape, and the way the Demon King looked at him seemed to grow more and more unsettling.

Shen Xi: ?

He hurriedly wrapped his robe tighter. "...Wait, we're the same person."

But the Demon King gripped both his wrists. "If you're me, then I'll be even less willing to let you go."

Shen Xi: … (fainted)!

The Demon King's inner thoughts: After finally finding a familiar, warm treasure amid a thousand years of lonely days hiding murderous intent, how could I let you run away? I can only hide you away.

CP: [Bottom] Shen Xi, age 23 x [Top] Ji Mian, looks 28 but is over a thousand years old

They look about the same age, since they are the same person at different stages of life.

[Reading Guide]

1. 1v1, HE, self-ship, each other's one and only, and everything is a first for both of them.

2. A nontraditional narcissistic romance: Whether it counts depends on your taste, since everyone has a different definition of the genre.

3. Nontraditional vampires: vampires are simply a species, and everything else is my own extensive worldbuilding. This is not traditional Western fantasy, but an alternate future setting. Please don't overanalyze it. The entire plot serves the romance, and the focus is on their interactions.

4. The System only helps the romance along and does not affect the bottom's agency. It plays a very small role later, though it is essentially connected to the two of them and involves spoilers.

5. The top has strong feelings for the bottom. He's obsessive and controlling at first, and the content gets a little dark. Readers who prefer gentle older tops and sweet doting romance, please read with caution. Extreme character loyalists, please stay away.

6. A madness-filled palate cleanser. Some additional content warnings are in the first chapter author's note. Feel free to stay or leave as you please. If anything makes you uncomfortable, please leave right away. Never force yourself! Please keep the comments friendly ^^
