Cen Xun is a folklore professor at H University—beautiful, young, and captivating countless students in every class.

His life follows a monotonous routine, calm and uneventful, until an unexpected fall from a building. After resurrecting, Cen Xun suddenly discovers the secrets of this world.

For example, his life is actually repeating in a daily cycle: his husband prepares breakfast on time, drops him off at the university precisely on schedule, and in the evening, their time spent in intimacy is accurate to the second.

For example, he can hear the thoughts of those around him and learns that a group of individuals calling themselves “players” has infiltrated his students.

“Awooo! Our professor is just too stunning—third time checking in! Gotta take a selfie!”

“I can’t bear to part with our gorgeous professor. It’s rare for the dog game to have such a beautiful model, but sadly, H University is about to become a B-rank Eerie Domain. The professor isn’t a main character, so he’ll probably be cannon fodder in the end, wuwuwu.”

Cen Xun sneered. Cannon Fodder? Impossible.

At last, his dull life encounters a ripple. Amused by his own dark sense of humor, Cen Xun decides—why not stir the waters even more?

Holographic Horror Game [Nightmare World] Forum

Player 1: “Can the officials explain the B-rank Eerie Domain ‘Lost Campus’? I teamed up with a top-100 ranked expert to run it three times, and we got completely wiped out every time. How is this fair?”

Player 2: “Are you living under a rock? This instance was upgraded to an S-rank instance ages ago. Apparently, the boss absorbed other Eerie Domains and even allied with several Domain Lords. The monsters from different instances now visit each other like neighbors—winning is a joke.”

Player 3: “I’ve lost all hope. The Dean of the Media College is the S+ level ‘Thousand-Eyed Reporter’ from the TV Station instance, the Dean of Computer Science is an infamous entity with game-wide bounty, and even the cafeteria worker at the food window is an S-level Domain Lord! So, tell me, what rank is the Chancellor?”

Player 4: “My beloved Professor Cen is kind, gentle, and weak—surrounded by all these powerhouses, he’s definitely going to be bullied, wuwuwu.”

In 《Nightmare World》, all players share one common White Moonlight.

Before transformation, he was a cold-faced yet warm-hearted folklore professor who willingly sacrificed himself to save students from the corrupted Chancellor—earning the tears of countless players.

After transformation, he became a mysterious and eerie existence, yet still showed goodwill toward players. To protect his students, he dared to challenge Domain Lords alone, taking on high-level monsters in extreme battles.

He was the one pure and noble soul among demons and ghosts.

Players, deeply moved by their professor’s kindness, swore to repay him—rushing to the front lines, willing to spill their blood in his name.

As the game progressed, the system announced the final mission: all players were about to face the ultimate boss—”Gui Sun” level Eldritch God.

On the day of the final battle, players stood ready for war, eyes locked on the highest point, where top-tier nightmare entities gathered.

Then, a familiar figure appeared with elegance.

“My dear students, and my… husband. I hope you have been well.”

Every player’s pupils shook in horror.

Wait, my gentle and delicate White Moonlight Professor is actually the Final Boss?!

One night, after discovering the truth about this world, Cen Xun hurried home, intending to take his husband and escape.

But as he packed their clothes, he suddenly heard his husband’s thoughtful inner voice:

“His behavior has suddenly changed. Could there be a bug in the program? Should I have the team work overtime to fix it?”

…

Cen Xun slowly stopped packing, lifted his head, and gave his husband a deadly smile.

“He smiles so beautifully… I want to keep him trapped in this game forever.”

His seemingly upright and abstinent husband was secretly thinking such things.

Pre-Reading Guide:

1. The shou belongs to the antagonist faction, with questionable morals—don’t enter if you dislike.

2. Age gap (younger gong × older shou).

3. Non-human. The shou is not human.

4. Over-the-top shuangwen. The couple has a love-hate relationship script, and the hate is rather intense (but the love is also super strong).
