[All] Yuk Seong-jae has grown up so well~~

I didn't see Yook Sungjae on Zico's Artist, but I saw it on YouTube~~

How did you grow up so well~~~?

The world's most playful and cute Yook Sungjae

BTOB is good at all songs, but they are the golden youngest who can do everything from singing, rapping, acting, and variety shows.

I'm so happy to have joined Synchroyou this time~~

The solo song is also really good.. and the vibe is totally manly now??
