FYI: Hyunjae’s parents have 3 children. Hyunjae is the youngest child and the only son. That means Hyunjae has 2 sisters, both of whom are older than Hyunjae. He has 2 nuna! As far as I know, Sister #1 is still unmarried. Sister #2 is married, she is the mother of Hyunjae’s niece Yujin, whose picture Hyunjae posted on his Instagram account recently.
Even though Hyunjae is the youngest child, but because he is the only son, he became the head of the household when both his parents got sick and when his father eventually passed away.
I am not sure what Hyunjae’s mom’s illness was, but I remember reading somewhere that she had to undergo throat surgery.
