From Junhoe’s Sister Koo Ye-jin to Yunhyeong’s Sister Song Eun-jin, Let’s Get to Know iKON Members Siblings!

Esther Kim (Donghyuk’s Sister)

Kim Donghyuk, also going by the stage name DK, has the roles of vocalist and main dancer in iKON. He was born on January 3rd, 1997, and was raised by his mother, since his father passed away when he was 8 years old. Donghyuk also has a younger sister and her name is Esther Kim.

There is not much information we could find out about his young sister. But there are some fans who say that his sister is still a student and currently studying in Atlanta.

Donghyuk once said that if he has to introduce his young sister to his fellow members, he wants to introduce Esther to Hanbin even though Donghyuk’s sister likes another iKON member, Yunhyeong a lot.


This guy is the youngest and tallest member in the boy band iKON under YG Entertainment, and his name is Jung Chanwoo. He was born on January 26th, 1998. Prior to his debut as an iKON member in 2015, Chanwoo had gained popularity as an actor and was well known for playing the younger counterpart of Lee Min-ho in both Boys Over Flowers (2009) and The Heirs (2013).

Out of all iKON members, Jung Chanwoo is the only member who does not have siblings because he is the only child in his family. Chanwoo was raised in Gyeonggi Province, South Korea, where his parents still live.

Jung Chanwoo was the last member to join iKON, through the Mix & Match reality survival show in 2014.

Honorable Mention: Kim Han-byul (B.I’s Sister)

Kim Han-bin, or better known as B.I, was the leader of the boy band iKON. Unfortunately, a while ago B.I decided to withdraw from the group that raised his name due to tripping over a drug scandal in 2016.

In his group, B.I was known as a very charismatic leader. But who would have thought that B.I is such a loving brother. B.I has a sweet little sister who is 15 years younger than him. His younger sister’s name is Kim Han-byul and she was born on February 18th, 2011.

B.I is very close to his younger sister and is often caught on camera carrying his younger sister. Han-byul has also appeared in MBC’s pilot program The Game with No Name with her brother B.I.
