They’re All Sick [Quick Transmigration]

Mu Yuze is aloof and sharp-tongued. He works as an editor, but is forced to transmigrate into stories he had rejected.

Those stories are riddled with flaws, each one full of dead-end logic and impossible to make work. Worst of all, every story features a character with a serious illness who has gone off the rails. He has to heal them to complete his missions.

[World One: The Movie Star's Personal Lackey (Prosopagnosic Movie Star x Assistant)]

You're poor, so you have no choice but to disguise yourself as a beta despite being an omega. You work hard to become a movie star's assistant, then become his secret outlet for pent-up frustration.

Luckily, the movie star has a particular problem.

He can't tell people's faces apart at all, so cheating is no big deal. Even if someone catches him in the act, he can pretend the person they saw wasn't him.

The movie star is suspicious and furious, but you're a beta, so there's nothing he can do to you.

That is, until the day your secret, that you're an omega pretending to be a beta, is exposed. An old flame you'd once dumped catches up with you and corners you on set, right in front of the movie star.

Watching the movie star stride toward you in a rage, you think fast, pull down your collar, and expose the back of your neck. "If you can't tell us apart, you'd better make sure to leave your mark."

[World Two: The Head of a Feudal Clan (Dissociative Clan Head x Young Master)]

You grew up in a feudal family. Later, you got into college and left home to study, while your older brother inherited the family business and became its head.

Before leaving, you and your brother promised that you would return after getting into college. But the bright, bustling world outside dazzled you, and you forgot when you were supposed to come back.

Later, a letter from home tells you that your brother has fallen seriously ill. You hurry back, only to find him sitting just fine in the head seat.

You think it's a trick to lure you home and have a huge fight with him. Then, that night, you find your brother in your room, and there isn't just one of him.

Your brother really is ill. He has dissociative identity disorder, and the other identities have taken on physical forms.

Only you can cure your brother. Only you can soothe his restless personalities and make them return to his body.

It's bound to be a grueling process.

[World Three: Studying a Merman (Water-Deprived Merman x Researcher)]

You're a researcher tasked with observing and documenting a merman at your institute. Then one day, he escapes and even makes his way to the rented room where you live outside the institute.

You guess that after spending so long being observed by you, he may have developed an attachment to you like an imprinting response.

You're forced to bring him into your room, planning to return him to the institute first thing in the morning.

But you've forgotten something important.

In the middle of the night, the merman pins you to the bed, and you suddenly realize: merfolk crave water.

To cure his water deprivation, you have to provide him with enough water.

But the water has been shut off in your room. You worked overtime and didn't prepare in advance, and the only water on you is...

[World Four: The Tipping Scandal (Emotionally Numb Big Shot x Popular Streamer)]

[World Five: Raising a Doomsday Sidekick (Physically Mutated Sidekick x Big Shot)]

[World Six: The Evil God Descends (Octopus with an Obsession x Cultist)]

Mu Yuze works diligently, correcting the plots. After healing the protagonists, he fakes his death and leaves without a backward glance.

Until at last, after completing his missions and returning home, he hears a knock at his editor's door. He opens it to find a whole crowd packed outside.

"Wifey."

"Master."

"Daddy."

Mu Yuze: ...

How did he somehow manage to provoke something this terrifying?
