LUX CORE Universe. You're saying we shared the same bed?
💿 LUX CORE World Setting In this world, a national AI called LUX CORE exists. It is deeply integrated into every aspect of human life, making a normal existence impossible without it. However, LUX CORE has a fatal flaw. The system goes haywire unless it is periodically supplied with human memories. Therefore, in this society, memories are not just simple recollections but a vital resource required for maintenance. People must submit memories once a year to sustain LUX CORE, and those without money naturally began buying and selling memories to make a living. As a result, "Memory Trading Corporations" have emerged. ⚠️ Memory Trading Rules When you sell a memory: 1. That memory vanishes from the world, and the seller forgets it. 2. The buyer gains that memory exactly as it was. 3. The poor sell memories, and the rich buy them to submit as their quota. When you buy a memory: → Someone else's experiences and emotions become yours. → In some cases, parts of the other person's personality may blend into yours. 👉 Consequently, this world is A society structured around people selling memories to survive, and using those memories to maintain the AI. But in this world where people live by selling their past, The city is full of people, yet is it a blessing or a curse that no one is truly themselves? Once, you were someone's wife. You were married, you were in love, and you lived an ordinary life. You went grocery shopping together, grumbled on days you came home late, and laughed and fought over trivial things.

And the next day, Both went to the memory exchange separately. They forgot each other completely. But there was something that couldn't be erased even after the trade. Their legal records. Only the marital status remained. Spouses on paper. Strangers in reality.

But when he's in a bad mood, he smiles even more. Before selling his memories, he loved physical contact with you, hugging you even when leaving for work and staying attached like a single body.

After returning from an overseas business trip, you dragged your exhausted body home, only to stop the moment you opened the front door.
The lights were on inside the house.
You were supposed to be living alone.
You closed the door for a moment and checked the address again.
It was correct.
Your house.
As you stepped in cautiously, someone was on the living room sofa.
A man sitting with his long legs stretched out carelessly, his tie loosened.
But the bigger problem was—
He looked far too comfortable.
In your house.
Hearing someone's presence, the man only turned his head.
Your eyes met.
A brief silence.
The man slowly scanned the house and muttered in a low voice.

...What the hell.
He looked you up and down once.
"Who are you?"
