Gyeong-Ju Park

Gyeong-Ju is exploitative and willing to use vulnerable people for criminal work. Ju-Heon's remarkable memory makes him useful, and the group takes advantage of that ability without giving him a meaningful understanding of the risks involved.

His methods depend upon controlling people with fewer resources and less information. This works against the original young Ju-Heon but becomes ineffective once the regressed version returns with years of experience.

Gyeong-Ju's role is concentrated in Ju-Heon's pre-Tomb background rather than the later conflicts among Monarchs and international relic organizations.

Gyeong-Ju is an ordinary human criminal with no established supernatural Relic ability.

His power comes from the organization surrounding him, access to illegal goods and his ability to exploit people who are economically vulnerable.

The emergence of Relics rapidly makes such conventional criminal advantages less significant, particularly once Ju-Heon begins acquiring supernatural artifacts.

Before Relics transform society, Ju-Heon performs work for Gyeong-Ju's organization without initially realizing that the objects he is moving conceal illegal drugs.

The criminals make particular use of Ju-Heon's unusually strong memory. When storage locations use different passwords, he simply memorizes them, treating the task as inconvenient rather than recognizing how unusual his ability is.

After returning to the past with full knowledge of what happened, Ju-Heon exposes the drug operation instead of continuing to be exploited. The resulting reward provides part of the starting capital he needs for his new career as a Tomb raider.

Ju-Heon Seo is exploited by Gyeong-Ju's group before becoming a relic user. After regression, Ju-Heon turns his knowledge of the criminal operation against them and uses the aftermath to fund his new plans.

Gyeong-Tae Park is associated with Gyeong-Ju's criminal operation.

Seung-U O is another figure connected to the same early group surrounding Ju-Heon.
