Jung Kim
Jung Kim is Min's best friend. 11 months prior to the start of the series, Jung went missing with most of his classmates believing him to be dead, except for Min. At the start of Parallel City he comes back after 11 months, albeit with amnesia.
~!It is revealed that this Jung is actually from Earth 1 and is the doppelgänger of Min's best friend. Since he did not experience the Erasure symptoms, the Jung Kim of Earth 2 had died. Despite not having any memories of Min or his friends, he is taken aback by Min's kindness to him. He fights for Min throughout the series and tries to pay back this kindness.
Jung Kim on Earth 1 was originally a slave for the Dawn Locust group, and was used as a scout to find DLS's at the Incheon Factory. After a massacre, he grabs a DLS from a dead teammate and comes to Earth 2.!~
