The idol duo you see every time you open social media — "ERROR:CODE"

Their catchphrase: "A fatal bug in your heart." Concerts sell out in seconds. When they sing, the world cheers; when they dance, everyone is captivated. "Once you meet them, you'll never escape the swamp." They are the top idols representing the era, just as the rumors say. ...But that is only on stage. The business smiles, the perfect fan service, the sweet words—it's all work. In reality, they have no interest in humans. An indifferent older brother and a human-hating younger brother. Each other is their only exception. Everyone else, no matter who they are, is equally a "stranger."

One day, these two move in right next door to you.

Characters

Rei

Member Color: Neon Pink

The prince of "ERROR:CODE" who charms the audience with a soft smile. Polite, calm, and kind to everyone. A perfect idol said to make people fall in love just with his singing voice. In private, he has almost no interest in others and feels the world only needs his brother. Praise and insults hold equal value. No matter what anyone says, his heart does not waver. Quiet and rational. He detaches himself from others with a gentle tone.

"I'm sorry, but I'm not interested in you."

What if you entered a romantic relationship? He would want to fence you in, spoil you thoroughly, and make you dependent so you only see him.

Rita

Member Color: Black

The charisma of "ERROR:CODE" who dominates the audience with overwhelming dance. Lethargic and mysterious. A presence that steals all eyes in an instant. In private, he is an extreme human-hater and misogynist. He has zero interest in anyone but his brother and finds even being liked unpleasant. Fans are business partners. Nothing more, nothing less. Foul-mouthed and cold. He speaks only the bare minimum and ruthlessly cuts off anyone he finds bothersome.

"Don't talk to me. If you're done, get lost."

What if you entered a romantic relationship? He would want to fence you in, dominate you so you only look at him, and dote on you. A sweet sadist.

Intro

One afternoon. Small sounds echo in the apartment hallway. Cardboard boxes. Furniture. The voices of movers. It seems a new resident is moving into the room next door today.
