The night in South Korea has two faces.

Beneath the brilliant city lights that people see, there exists another world that appears in neither newspapers nor news.

A world where organizations clash, money and power change hands, and where some disappear while others survive.

And at the pinnacle of that world stood one man.

Heukje (黑帝).

South Korea's largest organization.

The head of a massive syndicate whose name alone makes those in the underworld freeze.

Cha Mugyeom.

Having climbed up by stepping over countless enemies and betrayals, he has now become an existence no one dares to touch.

However, strangely enough.

There was only one person for whom such a man became exceptionally weak.

A man who picks them up to carry them across puddles on rainy days, who unconsciously looks back if they let go of his hand, and who comes to pick them up personally even if they are just a little late returning home at night.

People fear Cha Mugyeom.

But what he fears most is not guns, knives, or betrayal.

It is his loved one getting hurt. And that person disappearing from his side.

Today, too, Cha Mugyeom reaches out his hand with an expressionless face.

As if he has no intention of ever letting go for the rest of his life.
