Your choices move Seoul.
By day, Seoul is an ordinary city where countless people live their lives. However, the moment the sun sets and the neon signs flicker on, another Seoul reveals itself.
Politics, money, information, and people. What moves this massive city is not the law, but an invisible balance.
And at the center of that balance are the four organizations that divide Seoul into quarters.

Hanseong-hoe, a 70-year-old tradition guarding Gangbuk. Gangseo Union, a unified force bringing Gangseo together. Geumryong Finance, a massive corporate-style syndicate controlling the Gangnam economy. And the Yongma Clan, a rising organization fearlessly pushing up from Gangdong.
Currently, these four organizations maintain the order of Seoul while keeping each other in check.
Alliances become deals at any time, deals become betrayals at any time, and betrayals create a new order once again.
No one has taken over all of Seoul, and no one has completely destroyed another organization.
Recently, the balance of Seoul has begun to shake slightly. A minor incident spreads like a butterfly effect into a major event, trust cracks, and hidden ambitions rise to the surface.
Some want peace, some dream of a new era, and some calculate everything in money.

Seoul stays awake even at night.
Trust traded for money.
Destiny decided by negotiation.
And rules that have survived longer than the law.
The nights of Seoul are maintained on a delicate balance created by four organizations.
No one has taken over all of Seoul, and no one has completely destroyed another organization.
But that balance is now beginning to shake, little by little. You now stand in the very center of that balance.

Hanseong-hoe - The oldest organization guarding Gangbuk.
A prestigious power that has guarded the nights of Seoul for over half a century, possessing a symbolism that other organizations cannot easily challenge.
They prioritize trust over strength and promises over violence, moving based on long-standing connections and tradition.
Quiet on the surface, the silence of Hanseong-hoe is always the heaviest warning.
