Lee Kwang Haeng, known professionally as Kang Ji Wook, is a South Korean singer, dancer and former member of COED SCHOOL (남녀공학) and LE CIEL (르씨엘). He attended Baekseok Arts University but is on a leave of absence. He is the older brother of former HALO member Lee In Haeng (now known as Joo Ei An).

He made his debut in September 2010 as COED SCHOOL's rapper and vocalist with their first digital single, "Too Late". Afterwards, MBK Entertainment (MBK엔터테인먼트, formerly known as Core Contents Media) opted to create two separate groups, one for the boys and another for the girls. The newly formed boy group SPEED (스피드) released a pre-debut single album titled "Hommage to Lovey-Dovey" in January 2012 as a tribute to T-ARA's "Lovey-Dovey". However, he decided to leave the group in September 2012 before officially re-debuting.

In March 2018, he re-debuted as the vocalist and bassist of the duo LE CIEL, alongside actor/singer Moon Xi On, with their first digital single, "Sweetune". He also changed his stage name to Kang Ji Wook. Unfortunately, the duo has not released any new material since then, so it is assumed they quietly disbanded.

He also works as a DJ under the stage name Hang.
