Click-B member Kim Sanghyuk has quietly built a business portfolio that far surpasses his earnings as a celebrity. The revelation came during his appearance on Channel A's Groom Class Season 2 on July 16, where he opened up about his ventures beyond entertainment.

Kim Sanghyuk operates a tailor shop where he's directly involved in clothing design—work that's caught attention in high-profile circles. He's even designed suits worn in music videos by Rain. Beyond tailoring, his business interests span health patches and custom bags, all personally designed by him. When fellow guest Lee Seung Chul learned that Kim Sanghyuk had designed bags he'd already purchased twice, he was visibly impressed.

When asked about his businesses' revenue, Kim Sanghyuk indicated they generate monthly earnings equivalent to a senior corporate employee's annual salary—a striking figure that underscores the scale of his success.

The driving force behind this entrepreneurial push isn't simply ambition. Kim Sanghyuk has been candid about the anxiety stemming from entertainment's instability. Having experienced periods without work, he made a deliberate choice to build alternative income streams.

This calculated approach to his future contrasts sharply with his earlier career trajectory. Kim Sanghyuk debuted with Click-B in 1999 but saw his entertainment prospects severely damaged following a 2005 incident. He was accused of leaving the scene of a traffic accident and didn't report to police for roughly 11 hours. He received a suspended 10-month sentence and was ordered to complete community service. A subsequent press conference attempt to explain the distinction between drinking and driving became widely mocked, and that narrative followed him for years.

Despite the long shadow cast by that controversy, Kim Sanghyuk invested his time and energy into building something more stable. His latest TV appearance—his first as a divorced cast member on the show—has brought renewed attention to the thriving business empire he developed away from the spotlight. It's a reminder that for some K-pop figures, the most successful chapters of their careers may unfold entirely off stage.
