Yuk Sung Jae, a member of the boy group BTOB and a well-known actor, offered a sneak peek into his unconventional lifestyle on the recent episode of MBC's 'I Live Alone' that aired on May 23rd.

A teaser hinted at his appearance in the next broadcast after living alone for eight years. During the preview, Yuk showcased his black-themed home, expressing his profound affinity for the color. He humorously remarked that "The color of my heart is black," and shared how he transformed his living space into what he jokingly referred to as a "dark bat cave."

His residence starkly reflected his preference, with every corner adorned in black – from the living room and kitchen to the entrance and decorative elements. Even the show's mascot, Wilson, underwent a makeover, being dressed in black and dubbed the "Yuk Sung Jae Edition."

In one memorable scene, Yuk was seen leaping in the air while trying to apply black film to an air conditioner, illustrating his unwavering commitment to his distinctive style.

Yuk Sung Jae, who was born in May 1995 and is now 30, made his debut in 2012 as part of BTOB. He has since ventured into acting, attracting a devoted following with his versatile talents and distinctive persona.
