Kdrama Siblings

There is no doubt that kdrama siblings add spice to any K-series. From caring siblings to relatable ones, there’s a variety out there! Honestly, you can’t have as many types of foods as siblings in kdramas. On one side, you have those annoying and bratty younger siblings (Kim Hye Rin from She Was Pretty) that get on your nerves, while on the other are the older and more responsible ones. There are those sorts of siblings that wouldn’t let anyone harm their younger siblings, for example, Na Moo from Come And Hug Me. Another common occurrence that you might find in chaebol-based K-series’ is that the siblings would be fighting for the inheritance ever since they were born (ehm, Kim Won and Kim Tan from The Heirs, ehm).

In addition to that, the shenanigans and interactions between these siblings are so hilarious that the audience would continue watching the K-series just for them. Also, you can’t forget twins and their mischievousness. You could make a year-long compilation of a rich twin and a poor twin exchanging their lives in kdramas. However, nothing could get kdrama fanatics to get more teary-eyed than watching two long-lost siblings reunite. Dal Po and Ki Jae Myung, where are you guys at? Without further ado, we will be looking through all of the categories and naming kdrama fans’ favorite siblings of all time!

8. Jung Joo Hyung and Jung Jae Yi

Kdrama: Weightlifting Fairy Kim Bok Joo

Episodes: 16

Cast: Nam Joo Hyuk, Lee Sung Kyung, Kyung Soo Jin and Lee Jae Yoon

First up are some of the most good-looking siblings in a kdrama, Jung Joon Hyung and Jung Jae Yi. These two are actually not blood-related, so it is quite pleasing to see them getting along. Jung Joon Hyung had been abandoned at his aunt and uncle’s place by his mother when he was a little toddler. His cousin Lee Jae Yeon, ever since Jung Joon Hyung started living with them, cared for him and loved him as if they were a real family. They never had a hitch in their relationship until Jung Joon Hyung’s love interest started liking his older brother. It, of course, made things a bit uncomfortable and made Jung Joon Hyung a bit frustrated that his elder brother doesn’t even notice that Kim Bok Jo has a crush on him. However, as time passes by, the brothers make amends and clear the misunderstanding.

Baek In Ha is a crazy shopaholic and would do anything to get money on her hands so that she could hit the shop with her friends. She always asks her younger brother Baek In Ho for money, and he unwillingly gives her what she wants every time. Plus, fans loved the determination to protect her brother at all costs (all though it failed miserably). Of course, romance and the second-lead syndrome were some of the most significant parts of the K-series. The audience finds these siblings’ relationships precious.
