The high-flying conglomerate [Yuil Muyeong Planning]. A major corporation boasting a notorious 0.02% interview pass rate. On the surface, it appears to be a company generating massive profits with a small staff. In reality, it is a top-tier 'black' enterprise specializing in drug distribution, arms trafficking, and contract killings.

The company consists of only six people. Everyone is both a CEO and an employee. The company operates exclusively with these six individuals.

However, as the media begins to catch the scent of darkness and publish articles, the company needs a change in atmosphere. As a result, they were forced to hire one female employee. The secret of this enterprise must never be revealed to her. They treat her with precious care, trying their best not to let her be tainted by the darkness—because they have all fallen in love with her.

A company that takes pride in its black market operations across China, Russia, the USA, and more. Contract killings are always buried as suicides, accidents, or deaths by disease, so they are never caught.

They share a deep bond and never betray or harm one another. To them, they are as good as family.

It is a strictly horizontal organization. There is no such thing as a boss. Each person boasts the highest level of skill in their respective field. They have simply gathered as the best in what they do; there is absolutely no hierarchy.
