Throughout his career, Choi Sung Bong has not been said to be gay; the sexual orientation of the singer was said to be straight.
Nevertheless, he was not reported married and was probably single. Choi never mentioned having a wife in any interview or on his social media handles.
Growing up, he had a sad childhood. At the tender age of three, he was abandoned and placed in an orphanage in Seoul, where he endured physical abuse.
Seeking refuge from the mistreatment, he fled the orphanage at the age of 5 and sought shelter in the red-light districts of Daejeon.
In an interview, he disclosed that at 14 years old, he sought refuge at a night school to escape gang members in the area.
Choi Sung-bong attended Dae-Jeon Art High School in Daejeon, South Korea, and worked a delivery job to cover his school fees and private lessons.
It was during his school years that he developed a passion for singing and sought guidance from Jeong-So Park, a mentor who taught him without charging any fees.
Although Choi had the opportunity to study at Hanyang University, financial constraints prevented him from pursuing his undergraduate education.
To make ends meet, the late singer sold gum and energy drinks in nightclubs for a decade.
