Anja Djuricic was born in Belgrade, Serbia, in 1992. Her first interest in film started very early, as she learned to speak English by watching Disney animated movies (and many, many reruns). Anja soon became inspired to learn more foreign languages to understand more movies, so she entered the Japanese language and literature Bachelor Studies at the University of Belgrade.

Anja is also one of the founders of the DJ duo Vazda Garant, specializing in underground electronic music influenced by various electronic genres.

Anja loves to do puzzles in her spare time, pet cats wherever she meets them, and play The Sims. Anja's Letterboxd four includes Memories of Murder, Parasite, Nope, and The Road to El Dorado.

There's nothing more romantic than a beautiful love story, and romantic K-dramas raise the bar high when it comes to true romance. Whether we watch the protagonists fall in love with each other or follow an existing romance developing over time, cheering for love and affection between two people who are meant to be is one of the greatest ways to spend our time on TV.

K-drama creators know how to create a long-lasting couple. It can be different from Western romances, as the love stories in K-dramas evolve slowly and deliberately, building a foundation that is meant to last. Though that can sometimes get boring and doesn't always evolve the narrative quickly, there is a lot of beauty in it, and the greatest K-drama couples can certainly prove that. Here are the eight most perfect K-drama couples of all time.

8 Oh Ae-sun and Yang Gwan-sik — 'When Life Gives You Tangerines'

Ae-sun (IU) and Gwan-sik (Park Bo-gum) in When Life Gives You Tangerines

When Life Gives You Tangerines follows Oh Ae-sun (IU) and Yang Gwan-sik (Park Bo-gum) across decades, showing their lives from youth into adulthood. The drama spans about 50 years, from the 1950s to the 2000s, and centers around everyday routines, showing how time affects, shapes, and changes people. IU plays Ae-sun as a gentle but traumatized woman, while Park Bo-gum’s Gwan-sik is observant and consistent, which matters to Ae-sun more than he knows. Their relationship develops slowly, often in the background of larger events, but slowly becomes the show's emotional and narrative core.

Ae-sun and Gwan-sik aren't a fantasy couple with a whirlwind romance; their relationship shows a love built on endurance, patience, and consistency. They show up for each other even during times of distance and disagreement, displaying what a healthy and enduring relationship can look like. Additionally, the show gently shows their ups and downs and honors them individually and together as time goes by. There's a reason When Life Gives You Tangerines won the award for Best Drama at the Baeksang Arts Awards, and that's the chemistry between IU and Park, as well as the story that was written for them.

7 Yoo Shi-jin and Kang Mo-yeon — 'Descendants of the Sun'

Song Joong-ki and Song Hye-kyo

A couple look at each other in a war zone in Descendants of the Sun.

Descendants of the Sun follows Captain Yoo Shi-jin (Song Joong-ki), a special forces officer, and Doctor Kang Mo-yeon (Song Hye-kyo), a civilian surgeon, as their paths cross repeatedly, first in South Korea and later in a fictional war-torn country. The drama combines romance, military action, and medical crises, putting its characters in high-pressure situations that challenge their values and priorities. Song Joong-ki portrays Shi-jin as confident, charming, and dutiful, whereas Song Hye-kyo's Mo-yeon is principled, emotionally guarded, and unwilling to compromise her ethics. Their relationship evolves through various situations, but its biggest obstacle is the balance between their personal happiness and professional duties.

The push-and-pull dynamic between Shi-jin and Mo-yeon holds the series together. They challenge each other's perspectives but have an emotional connection that can't be denied. This conflict adds weight to the relationship beyond physical attraction or pure chemistry, guiding the narrative through various crises, violence, and disaster. Sometimes, the plot goes into melodrama territory, but it's all in the service of making Descendants of the Sun one of the greatest romantic K-dramas of all time.

6 Dong-baek and Hwang Yong-sik — 'When the Camellia Blooms'

Gong Hyo-jin and Kang Ha-neul

When the Camellia Blooms tells the story of Dong-baek (Gong Hyo-jin), a single mother who runs a small bar in a small seaside town, and Hwang Yong-sik (Kang Ha-neul), a local cop with an unwavering sense of hope and integrity. Dong-baek is emotionally guarded and worn down by years of social prejudice for being a single mother, whereas Yong-sik is open, earnest, and unafraid to express affection. Their romance happens at the same time as a mystery subplot about a serial killer, additionally commenting on gender biases and social scrutiny. The show achieves a great balance between warmth and suspense, with the relationship evolving gradually, built on a strong foundation.

What makes the relationship between Dong-baek and Yong-sik so great is how it depicts emotional safety. Yong-sik's love for Dong-baek is both unwavering and verbal; he believes in her openly and repeatedly, even when she doubts herself. On the other hand, Dong-baek is slow to accept his love, which quickly becomes one of the show's central emotional arcs. She heals and learns to trust, while he learns to be less impulsive and more patient. The chemistry between Gong and Kang is believable and wholesome, and their energy together is incredibly appealing. When the Camellia Blooms is often considered a realistic drama because of this slow-burning relationship that introduces real-life stakes.

5 Healer and Chae Young-shin — 'Healer'

Ji Chang-wook and Park Min-young

Healer follows the eponymous Healer (Ji Chang-wook), a night courier who often does illegal jobs, and Chae Young-shin (Park Min-young), a tabloid reporter searching for the truth behind a long-buried political conspiracy. Healer is hired to monitor and protect Young-shin, and their relationship grows secretly. Healer both protects and deceives Young-shin, but also inevitably falls in love with her. Healer is emotionally isolated, while Young-shin is emotionally open despite trauma. The show combines action, romance, and investigative thriller elements, with the protagonist taking on multiple identities as he becomes involved in Young-shin's life and resolves his own problems.

The romance in Healer is inextricably linked to the plot, so it anchors the show's narrative. The blend of investigative thriller and this romantic subplot provides each other with the necessary emotional depth to further the narrative. Themes of trust, identity, and vulnerability are all explored throughout the series and throughout the relationship between Healer and Young-shin. Healer is a very famous K-drama — a classic series that feels like one of those must-watch dramas for any beginner or K-drama veteran.

4 Choi Taek and Sung Deok-sun — 'Reply 1988'

Park Bo-gum and Hyeri

Reply 1988 is a coming-of-age drama set in a close-knit neighborhood in Seoul that follows five families and their children as they grow up. Choi Taek (Park Bo-gum), a quiet baduk prodigy, and Sung Deok-sun (Hyeri), an outspoken and emotionally expressive girl, form a relationship that develops within the larger ensemble. Taek is tender and honest, and Deok-sun is warm and vulnerable, fitting together well. Despite their romance not being the primary focus of each episode, it comes up and blossoms from shared storylines, small moments, and the natural passage of time.

The relationship between Taek and Deok-sun serves as an anchor for Reply 1988, and it reflects the show's larger themes of growing up, developing emotional maturity, and finding understanding. This message falls in well with the nostalgic tone of the show and depicts a coming-of-age story that feels lived-in. Reply 1988 would still be warm without the romance between Deok-sun and Taek, but the show itself and the viewers would miss out on one of the most emotionally resonant explorations of a love that develops quietly and over time.

3 Kim Shin and Ji Eun-tak — 'Goblin'

Gong Yoo and Kim Go-eun

Goblin follows Kim Shin (Gong Yoo), a former Goryeo military leader, who is cursed to live forever as an immortal goblin. Ji Eun-tak (Kim Go-eun), a high school senior who can see ghosts, enters his life after centuries of him waiting and being lonely. Gong portrays Kim Shin as weary and emotionally distant, while Kim makes Eun-tak resilient, bright, and emotionally open despite a difficult upbringing — which, if you noticed, seems to be a pattern among K-drama couples. The show combines humor, tragedy, and romance, relying heavily on symbolism and recurring motifs of fate and death, with the relationship between Shin and Eun-tak feeling both inevitable and doomed.

The relationship between the cursed soldier and the girl who can see ghosts is the foundation for Goblin's fantastical storyline. And while their bond helps the show stay remembered for its emotional impact, the age gap between the protagonists, or rather Ji Eun-tak's age, in particular, is a problematic part of the show. She isn't underage in the series, but she's still very young. Gong and Kim have an interesting, very endearing chemistry, and their performances are amazing. There's not much physical affection, but the love between them is palpable, which is why people love Goblin so much.

2 Baek Hyun-woo and Hong Hae-in — 'Queen of Tears'

Kim Soo-hyun and Kim Ji-won

Baek Hyun-woo and Hong Hae-in look at each other intensely in the Korean Drama Queen Of Tears.

Queen of Tears follows Baek Hyun-woo (Kim Soo-hyun) and Hong Hae-in (Kim Ji-won), a married couple whose relationship has deteriorated due to emotional distance, resentment, and unspoken pain. Hyun-woo is a conflicted and emotionally unstable man, and Hae-in is a restrained, prideful, and vulnerable woman. Their relationship comes to an impasse when Hae-in gets a cancer diagnosis. After learning about her illness, the couple reminisces on their marriage, wondering when the romantic phase ended and going into emotionally charged situations that bring unresolved feelings to the surface. The plot alternates between the past and the present, showing how they fell in love and where things started going wrong.

Queen of Tears revolves around this relationship, depicting love at its most uncomfortable stage. Instead of focusing on the part when they fall in love, the series wonders whether love can handle neglect, misunderstandings, and emotional exhaustion. Their dynamic is tense, but small moments of connection become more meaningful than any escalation, making Queen of Tears feel realistic and yet completely romantic and charming. The two actors have intense, beautiful chemistry that transforms the show into a character-driven exploration of marriage rather than a traditional romance.

1 Yoon Se-ri and Ri Jeong-hyuk — 'Crash Landing on You'

Son Ye-jin and Hyun Bin

Jeong-hyeok and Se-ri leaning against each other in Crash Landing on You.

Crash Landing on You follows Yoon Se-ri (Son Ye-jin), a South Korean businesswoman who accidentally lands in North Korea after a paragliding accident, and Ri Jeong-hyuk (Hyun Bin), a North Korean officer who finds her at the border and takes her in before she gets into trouble. Se-ri is sharp, emotionally guarded, and secretly vulnerable, and Jeong-hyuk is disciplined, reserved, and deeply principled. Their relationship grows despite them being under constant threat, influenced by political borders, surveillance, and danger. Crash Landing on You successfully finds a balance between romance, suspense, and humor, using its somewhat unrealistic premise to dive into human connection across ideological boundaries.

Se-ri and Jeong-hyuk's relationship turns the overall geopolitical stakes of the show into a very personal story about trust, hinting at the humanity that exists on both sides. Se-ri and Jeong-hyuk fall in love through acts of care, making their bond feel secure and genuine, and the show relies on their chemistry to help drive the story forward. Since Son and Hyun have an electric chemistry that feels fresh and enchanting no matter how many times you watch it, their stint in Crash Landing on You makes them the most perfect K-drama couple of all time. It'll be difficult to ever top them in terms of electricity and presence.
