Five On-Screen Sibling Bonds K-Dramas Got Just Right

Sibling rivalries, protective instincts (sometimes a little too protective), and unconditional love—we’ve all been there, right? And we see them in our K-dramas. From Moon Sang-tae’s adorable quirks to Oh In-joo’s efforts to give her sisters a better life, these stories have a way of capturing the real moments—sometimes messy, but often the beautiful reality of sibling relationships. Whether it’s Gu Jun-hee’s calm guidance or Lee Yeon’s brooding protectiveness, these K-dramas remind us that our siblings are our companions, confidants, and caretakers. Here are some K-drama sibling relationships that’ll make you feel like, “I got you, you got me!”

Gu Jun-hee and Gu Jun-pyo (Boys Over Flowers – 2009)

Gu Jun-pyo (Lee Min-ho) leads the hottest F4 clique at elite Shinhwa High School—an arrogant, rich, spoiled brat—or so it seems, for beneath his rough façade lies a sensitive soul, scarred by loneliness and a rough upbringing. But thanks to his older sister, Gu Jun-hee (Kim Hyun-joo), who brings a sense of calm to his life. When Jan-di (Ku Hye-sun), a scholarship student from a humble background, bursts into Jun-pyo’s world and challenges his ego, he’s forced to confront his vulnerabilities, increasingly falling in love with her, to the point that his mother starts scheming to tear them apart. And amid the chaos and struggle that follow, Jun-hee, like a steady support, guides Jun-pyo with kindness and insight, while also lending a helping hand to Jan-di, proving to be an unconditional and loving presence in their lives.

Moon Sang-tae and Moon Gang-tae (It’s Okay to Not Be Okay – 2020)

When a withdrawn children’s book writer, Ko Mun-young (So Yeah-ji), and a kind psychiatric ward caregiver, Moon Gang-tae (Kim Soo-hyun), meet, they find love and healing in their shared journey of self-discovery. But there’s another enlightening side to the narrative: Gang-tae’s commitment to looking after his autistic older brother, Moon Sang-tae (Oh Jung-se), and the latter’s emotions for his younger brother, making it a distinct portrayal of sibling love. Sang-tae’s emotional outbursts and thoughtful observations bring out the best in Gang-tae during his darkest moments. There’s this one specific moment that stands out, revealing Sang-tae’s depth as a person who isn’t just reduced to his challenges—that is, when he says, “Moon Gang-tae belongs to Moon Gang-tae,” it’s his awareness that Gang-tae needs to have a life of his own and prioritize his needs and desires, which he’s been quiet about all through. Their bond becomes a beautiful, gradual process of emotional give-and-take, highlighting the often-overlooked mental health issues and just how important mutual understanding is in such situations to heal and grow.

Lee Yeon and Lee Rang (Tale of the Nine Tailed – 2020)

Fantasy, action, suspense, horror, and romance swirl around two brothers, Lee Yeon (Lee Dong-wook) and Lee Rang (Kim Bum), who are poles apart. Lee Yeon is a gumiho dedicated to saving lives and is compelled to rescue Nam Ji-ah (Jo Bo-ah), a TV producer who jumps off his building to learn his truth and becomes entangled in his world thereafter. Lee Rang, in contrast, is a half-blood gumiho who holds conservative views about Lee Yeon because of a past misunderstanding, which fuels a toxic relationship between the brothers. Yet, on the inside, they are ever ready to protect each other. As the plot intensifies, they’re pushed to face their demons and rediscover the true meaning of brotherhood.

The Yeom Siblings (My Liberation Notes – 2022)

Shackled in their own prisons, the Yeom siblings—Ki-jeong (Lee El), Chang-hee (Lee Min-ki), and Mi-jeong (Kim Ji-won)—yearn for liberation. Ki-jeong’s desperate search for validation, Chang-hee’s suffocating sense of responsibility, and Mi-jeong’s complex love relationship and self-doubt all threaten to consume them. Yet, despite all of that and the cracks in their relationship, they’re together in their shared experiences and memories, especially the loss of their mother that rocks their world but brings them closer. So, even as they stumble and fall from time to time, they’re held together by each other, and in the humdrum affairs of daily life or the quiet moments of their country life, they begin to find their way to the liberation they’ve been looking for for a long time.

The Oh Sisters (Little Women – 2022)

Financial security has been a distant dream for the Oh sisters—Oh In-joo (Kim Go-eun), the pragmatic and determined eldest; Oh In-kyung (Nam Ji-hyun), the feisty and principled middle sister; and Oh In-hye (Park Ji-hu), the free-spirited and artistic youngest. Abruptly for them, things get messy when they find themselves with billions from a supposedly deceased friend and Korea’s wealthiest family, who will stop at nothing to keep the fortune for themselves. In-joo decides to use the money for a better life, while In-kyung digs into the mystery. Along the way, In-hye becomes a pawn in this game of survival, with clashing opinions seeming to threaten their bond. Still, love prevails, with In-joo and In-kyung doing everything they can to protect In-hye as they fight for their future and what they truly deserve.
