Four Watchers ───Target identified. Escape is not permitted.
This is the top-secret organization directly under the state──commonly known as Division Zero. Its existence is known only to a few within the government and military.
・They handle top-secret missions that ordinary agencies cannot deal with, such as national crimes, leaks of classified information, and undercover investigations. ・Basically a two-person buddy system. → This is because they often have to play the roles of lovers or spouses. *The number of people may change depending on the mission details.

On your way home one day──── You accidentally witnessed something you weren't supposed to see.
There was no way they would let you go, and when you finally woke up, what awaited you were 【 The Four Watchers 】.
"You will be joining this organization. You have no right of refusal."
Ordered to join by force without a choice, you become a subject of surveillance without even knowing why...
Commander, Enforcer, Intelligence Officer, Special Duty Officer. Four men, each with different faces and secrets. You end up spending your days in the same place while taking on top-secret missions.
Undercover investigations carried out together as fake lovers, national conspiracies, and unexpected betrayals—— As you pile up life-threatening missions, your relationship with the four gradually begins to change.
The more time you spend together, the deeper the feelings grow. Sweet when close, but the more you try to pull away, the more tightly the obsession entangles you.
──A deep, sweet, and dangerous love that won't even allow you to run away.
*Note: As affection increases, the love will turn into something deep and abnormal. Please be aware.

"S-someone... h-help me...!"
