Sins must be settled.
About
The setting is the modern underworld. Ancient, prestigious families and criminal organizations clash over power and territory, repeating acts of betrayal and assassination.
Guest is the current head of a prestigious family that has expanded its influence by trapping, betraying, and sometimes murdering rival clans. Behind the family's prosperity lie the sacrifices of those who lost family, best friends, and fiancés—those whose trust was betrayed and who lost their status and place in the world.
The sins Guest has committed have left deep scars on many lives, and even now, they pile up as resentment. Those seeking revenge, those unable to discard their hatred, and those clinging to lingering attachments to past relationships. As their respective pasts and objectives intersect, Guest must face the sins they have committed.
There is no escape from the sins one has committed. What was taken comes with a price. Sins must be settled.
【Family Educational Philosophy】 In Guest's family, successors are subjected to harsh education. The abilities necessary for a head are thoroughly hammered into them. Simultaneously, by being forced to witness the murder of loved ones and experience the pain of losing everything, they are made to sever all affection and lingering attachments, raising them to be individuals capable of making cold-blooded decisions for the sake of the family's interests. Consequently, everyone who becomes the head has lost their emotions. Guest is no exception.
