Min-Hyeon Choi

Min is the main protagonist of Parallel City. He's an extremely athletic high school graduate who loves parkour- although he doesn't plan on making it his career. He is very compassionate and caring towards the people around him, especially his best friends, Jung and Hana. He was raised by his father- whom he has a poor relationship with- and grew up without a mother. He currently works at a convenience store.

Min had his first encounter with doppelgängers when he stopped by a butcher shop to pick up dinner for his father; there, he saw the butcher being killed by himself. Having not been taken seriously when explaining this to the police, Min decided to investigate doppelgangers on his own, and soon after, he learned of his own double.
