Okay this is an issue that we all need to focus on right now. These two look too much alike to not be brothers.
Sunyoul is a vocalist in the rookie group, UP10TION. Being born on November 6, 1996, that makes him 19 yrs old.
Jungkook is also an vocalist in the popular group, BTS. He was born on September 1, 1997 which makes him only a year younger than Sunyoul.
I mean come on!!! Just look at them ^^
