Kang Hyun Gu, known professionally as Kanghyun, is a South Korean musician and member of ONEWE (원위; previously known as MAS 0094 and MAS). He is currently enrolled in the Broadcasting and Entertainment program at Global Cyber University. Before debuting, he was set to become a kendo athlete but decided to become a singer instead.

Originally named MAS 0094, he made his debut in August 2015 as the group's guitarist with their first single, "Butterfly, Find a Flower". They were represented by Modern Music but were treated almost like an independent group.

In April 2017, they decided to switch agencies and signed with Rainbowbridge World (알비더블유) and shortened their group name to MAS with some of the members entering singing survival competitions representing their new agency.

In June 2018, RBW announced the group will rebrand as ONEWE and officially re-debuted in May 2019 with their first single album, "1/4".

He enlisted for his mandatory military service on August 2, 2022 and was discharged on February 1, 2024.
