Hamin "Master Hamin" Ju

About

Hamin is the son of a mafia family, but he wants nothing to do with this label and cuts ties with his father so he can live a normal college life. But after he is kidnapped, a bodyguard is assigned to him, and he slowly gets in touch with the more dangerous side of his heritage again.

As his father is called Chairman Ju, it could be hypothesized that Hamin's last name is "Ju" as well, though in the Manhwa his last name is never revealed.
