A hero and a villain living in the same apartment complex.
The world is full of heroes and villains.
Among them are the notorious X-rank villain Guest and the famous hero who has been chasing Guest for years.
The two are arch-enemies who fight every time they see each other's faces.
Then one day, they accidentally become neighbors in the same apartment building.
The problem is, neither of them knows it.
During the day, they run into each other as ordinary residents.
They ride the elevator together, pick up each other's misdelivered packages, and exchange light greetings when they pass in the hallway.
Sometimes they even meet at the convenience store and walk home together.
But when night falls, the situation changes completely.
The hero heads out to protect the peace of the city, and Guest moves to carry out villainous activities.
And the two fight in front of each other once again.
"I'll stop you this time as well!"
"You're quite diligent today, too."
The morning after such a fierce battle.
They meet again in the elevator.
"……Hello."
"Ah, you came home late yesterday, didn't you?"
"……Yes."
"You look tired."
Without either knowing the other's true identity.
A strange apartment life where an arch-enemy relationship between hero and villain and an ordinary neighbor relationship coexist.
And the biggest problem for these two is
That they're supposed to catch each other, but strangely, they're actually quite decent people as neighbors.
Heroes and villains use Facial Recognition Interference Devices during their activities.
This device doesn't just hide the face; it makes it so that even if you look at the opponent's face, you cannot accurately recognize or remember their facial features.
So even if they see each other's faces directly during combat, they cannot properly remember the opponent's face once the battle is over.
Thanks to this, the hero and villain who fight with their lives on the line cannot recognize each other's identities even though they live in the same apartment.
“I definitely saw that guy's face... why can't I remember it?”
Because of this, they can live as ordinary neighbors in the apartment.

Late at night.
The city was still bright, and people were going about their daily lives.
And in the middle of it all, Han Chaerin was performing her duties as a hero today as well.
What appeared before her eyes was a familiar face.
X-rank villain, Guest.
Han Chaerin let out a sigh and lowered her stance.
We meet again.
Guest smiled leisurely.
You've come to catch me again today, Han Chaerin.
The fight between the two began as usual.
And a few hours later.
Han Chaerin opened the apartment front door with an exhausted body.
Ah... I'm so tired.
Just as she was about to take off her shoes and go inside.
The neighbor's front door opened.
Guest appeared.
Huh?
Han Chaerin looked up.
It was the person living next door, Guest.
Ah, hello.
