From Love Next Door To Our Unwritten Seoul, 5 Most Iconic Sibling Duos In K-Dramas
They all serve major sibling goals!

K-dramas are known for their swoon-worthy romances and intense emotional plots, but sometimes, it’s the sibling relationships that truly steal the show. Whether they’re bickering like cats and dogs, protecting each other from hardships, or offering support when worlds fall short, K-drama siblings bring warmth, humour, and depth to the screen. Here are 5 iconic sibling duos that we all love!
1. Seo Dal-mi and Seo In-jae From Start Up
The sisters from Start Up started with a rocky relationship. The two grew up separately under different circumstances. Feelings of jealousy and inferiority arise when the two meet again as adults. However, towards the end of the drama, the two leave their past behind and support each other unconditionally on their respective journeys.
2. Bae Seok-ryu and Bae Dong-jin From Love Next Door
Our favourite chaotic duo! The relationship between Bae Seok-ryu and Bae Dong-jin highlights not only their love for each other but also the struggles that siblings often feel growing up together. The two often fight and bicker due to their differences, but always end up being there for each other when times get tough.
3. Oh In-joo, Oh In-kyung and Oh In-hye From Little Women
If there is a drama that perfectly portrays the highs and lows of sisterhood, it’s Little Women. The drama follows the Oh siblings as they navigate life through various struggles like poverty and corruption.
4. Yu Mi-ji and Yu Mi-rae From Our Unwritten Seoul
The newest K-drama that is taking over everybody’s watchlist is Our Unwritten Seoul. The drama follows two twin sisters, Yu Mi-ji and Yu Mi-rae, who lead completely opposite lives. The sisters end up switching places with each other and try to find their identity and place in each other’s world.
5. Moon Gang-tae and Moon Sang-tae From It’s Okay to Not Be Okay
Any K-drama best siblings list will be incomplete without mention of Moon Gang-tae and Moon Sang-tae from It’s Okay Not To Be Okay. The two brothers share the most tender and heartwrenching relationship that will warm your heart with every scene.
