Korean Dramas That Focus On Just One Couple

Something About 1% - this is a cute, fluffy, contract romance drama that is almost completely focused on the couple. Each main character is fleshed out, with their own personalities, dreams, careers...it's nice to see how their lives grow together and how they get closer. Definitely recommend. Even has some steamy kisses!  - u/caninedesign

To My Star - this is a boy's love drama and is very nicely done. The main leads are polar opposites of each other. One is a top drama actor and the other is a poor kitchen chef. The end up cohabiting, going from arguing to each other to love. One of the few boys love that isn't a school coming of age drama. - u/caninedesign

You Drive Me Crazy - this is only 4 episodes, about 30 minutes each. It's about two friends who realize they have feelings for each other. For being so short, the character development feels natural and not hurried, and has just the right pace to tell a complete story.  - u/caninedesign

Semantic Error - this is a boy's love drama about two college students who start from enemies and become lovers. The banter is top notch, and is very sweet and funny at times. You can really feel the chemistry between the leads in every scene.  - u/caninedesign

Soundtrack #1 - this is a friends to lovers drama, only 4 episodes. The ML has been in love with his best friend for years and is above to give up when she realizes she loves him back. The acting is great, but the story is slow to develop and you don't get to see much time with them together as a couple.  - u/caninedesign

Bring It On, Ghost - Park Bong-Pal is a college student who can see and beat ghosts and so does part time job of exorcism in order to make money. He meets Kim Hyun-Ji, a high school ghost, through his part time gig and they join hands to work together as they help each other. The drama focused only on this main couple in terms of romance though it also has mystery and crime. I really loved the chemistry between the main leads despite the huge age gap between the actors. They were adorable together and the drama too was pretty entertaining especially the scenes where they perform exorcism together.  - u/Fatooz

Happiness - Yoon Sae-Bom is a special agent who is smart and quick witted. Jung Yi-Hyun is a detective and both him and Sae-Bom who're high school friends get entangled in a new virus case. They both move to a special apartment through the civil servants quota and the apartment gets infected with the virus. Both of them fight against all the "villains" and "zombies" together. There's very minimal romance but whatever crumbs we get were amazing. I especially enjoyed their couple dynamics because of the understanding and slow burn romance. Their chemistry was great!  - u/Fatooz

Healer - Seo Jung-Hoo famously known as "Healer" is a special night courier and performs various jobs for his clients. He gets intrigued by one of his client's request and ends up meeting Chae Young-Shin a second-rated tabloid writer. He disguises as an intern at her company and slowly slowly falls for her. The drama mainly focuses on this couple and their romance. Both Ji Chang-Wook and Park Min-Young had such amazing chemistry. Their romance is a slow burn but I loved their relationship and the maturity in their relationship. It's one of the best action dramas I've seen and Ji Chang-Wook is absolutely killing it!  - u/Fatooz

The King: Eternal Monarch - Lee Gon is the king of Kingdom of Corea, parallel universe, and ends up meeting Jeong Tae-Eul, a detective in Republic of Korea and the drama focuses on their forbidden love story. It's a mix of sci-fi, mystery and romance but unlike the popular opinion, I really enjoyed the romance of our main leads. Their relationship was everything that I look for in a KDrama couple. They had great communication, they had zero tropes, they had zero stupid misunderstandings and zero noble idiocy. I also really enjoyed Lee Min-Ho and Kim Go-Eun's chemistry, it was so organic.  - u/Fatooz

The Red Sleeve - The drama is about the forbidden romance of Yi San and Sung Deok-Im, and is based on a true story. It only focuses on their love story and all the barriers between their love. Lee Jun-Ho and Lee Se-Young were phenomenal in their roles but I truly enjoyed their chemistry. They added a different layer to their character and their acting totally immerses you into the story and the romance will truly touch your heart!  - u/Fatooz

Tomorrow With You - Yoo So-Joon can time travel and he once sees the future that him and Song Ma-Rin are dying on the same date. He approaches her in order to change his future. Ma-Rin is a once famous child actress is now a struggling photographer and a terrible drinker. As they both come closer, can So-Joon truly be able to change the future and what will happen when Ma-Rin finds out that he's a time traveler. I absolutely loved the drama for its romance. Lee Je-Hoon really proved that he can do any genre amazingly and he shared beautiful chemistry with Shin Min-Ah. The sexual tension between the two was so good. Even though the drama took a good 7 episodes to convince me, I'm glad I stuck through it because it was actually worth my time!  - u/Fatooz

Youth of May - Hwang Hee-Tae is a brilliant medical student at Seoul National University but an unfortunate incident makes him afraid of performing medical practices again. He meets Kim Myung-Hee, a nurse, under unfavourable conditions and they both fall deep in love. The drama is set around the events of the Gwangju uprising but the main romance was so well done. Hee-Tae and Myung-Hee are a lovely couple and their chemistry was off the charts. I will highly recommend this for the performance and romance!  - u/Fatooz
