Ko Young-wook says he refrained from joining karaoke singers for fear of being reported after hearing his hit song

A post by Ko Young-wook, former member of the group Roo'ra, in which he shared his reaction to hearing one of his past hit songs at a karaoke room caught the eye.

On Thursday, Ko posted on his social media X account, "I heard a familiar song coming from the karaoke room hallway and went in, thinking I might help with my part, but I held back for fear of being reported." He also posted a video.

The video captured the sound of someone singing Roo'ra's hit song "3! 4!" at the karaoke room. Released in 1996, the track is one of Roo'ra's representative hits.

Ko debuted as a member of Roo'ra in 1994 and went on to work as a singer and broadcaster.

He was later prosecuted on charges of rape and forced indecent acts against a minor, and in December 2013, the Supreme Court finalized his sentence of two years and six months in prison.

He was also ordered to have his personal information disclosed for five years and to wear an electronic tracking device for three years.

Ko completed his sentence and was released from prison in July 2015.
