Yook Sungjae recently showed his fellow BTOB members some love!

BTOB’s Yook Sungjae and Hyunsik are currently completing their mandatory military service after enlisting together in May 2020. The four members of BTOB who have already completed their service (or are not required to serve, in Peniel’s case) are currently promoting as BTOB 4U, having released two albums and competed on Mnet’s “Kingdom: Legendary War.”

BTOB 4U made a comeback on August 30 with the special album “4U: OUTSIDE,” with Hyunsik having written, composed, and arranged one of the songs before his enlistment.

On August 30, Yook Sungjae shared a screenshot of the album cover on his Instagram Stories and wrote, “The group I’m really into these days. Congrats on BTOB 4U’s comeback! Hwaiting!”
