The "small boy" in BTS is generally understood to be Jungkook, the youngest member of the group.
Jungkook, whose full name is Jeon Jung-kook, was born on September 1, 1997, making him the maknae (youngest member) of BTS. While he is no longer a "small boy" in the literal sense, the nickname persists, especially amongst ARMY (BTS's fanbase), often endearingly referring to him as "Kookie" or "Golden Maknae." The term "Golden Maknae" highlights his exceptional skills and talents across singing, dancing, rapping, and other areas. His youthful image during BTS's early years contributed to this perception.
