The Central World is suddenly struck by "Chaos Corruption," sending all the master-disciple romance worlds spiraling into dark, tragic endings. The aloof teacher is dragged into the mire, his proud integrity shattered to dust, while the sneering laughter of his corrupted scum disciple becomes the only soundtrack. System 233, a corruption-entity capture system, is given an urgent mission: bind to a Host and patch up the broken little worlds.
The Host flips through the pages with a cold expression. "What is this script full of mosaics supposed to mean?"
The System's voice wavers. "...Since you're an outsider, Host, the world’s corruption entities have to recognize you as corrupted first. Put simply... you have to play a corrupted scum disciple and treat your teacher terribly."
The Host: "I'll handle the cosplay, you capture the corruption entities. Clear division of labor."
The System: "Yay!"
A few days later, the System breaks down and howls, "What happened to the humiliation? The cruel words? How did you turn a tragic ending into a happy one?"
[World One]
You are the family's illegitimate Alpha, a child kept out of sight. The fighting arena is your only home, and yet you hate the academy's combat instructor more than anyone. He is the Alpha about to marry your Omega brother, outranks you in the inheritance line, and beats you so badly in the arena every time that you can't even get back up.
You lick your wounds, seething: One day, I'll make him pay back every last bit, with interest.
On the day of your second differentiation, you become an Enigma at the very top of the hierarchy. Later, during his rut, he loses control, and you corner him in the equipment room.
The System rubs its hands together excitedly. "Bite his gland! Quick, bite!"
The Host quietly moves his canine teeth away. "If it hurts, bite me. Don't hurt yourself."
The System: ?
[World Two]
You are a spoiled rich kid who never studies, and you despise the aloof, taciturn teacher of ancient texts. He is kind to everyone but as cold as ice toward you, and always favors your nemesis.
Then an unjust case of "academic misconduct" gets him expelled from the research institute. With no other choice, he swallows his pride and comes to ask you for help.
A shadowy excitement suddenly wells up inside you, dark and despicable.
The System prompts frantically: "Force him! Humiliate him! Say, 'So now you're the one begging me!'"
The Host: "...I can't violate public decency and morality."
The System: ?
[World Three]
You are a prince raised in the cold palace. No matter how diligently you study, you can't win the favor of the upright Grand Tutor. Only when you see his warm affection for the Crown Prince do you realize that so-called "uprightness" is merely a mask for currying favor with the powerful. Then a prophetic dream shatters every last hope.
In the dream, you ascend the throne, but the Grand Tutor helps the Third Prince rebel and drives you into a desperate corner, spitting out, "A star of calamity, doomed to bring ruin to the empire if you become emperor."
When you wake, you proceed with careful plans at every step and ascend the throne. On the day the Third Prince is exiled, the Grand Tutor kneels before the palace gate, trembling.
The System jumps up and down in a panic. "Make him suffer! Make him admit he was wrong!"
The Host offers him a cushion. "The ground is cold. Kneel on this while you talk."
