1. Twinkling Watermelon (2023)

Genre: Fantasy, Romance, Youth Drama
Episodes: 16
Seol In-ah’s Role: Choi Se-kyung / On Eun-yoo
Where to Watch: Netflix, Prime Video, Zee5, Viki

What happens when a young musician travels back in time and discovers that his parents’ love story is nothing like he imagined? That is where Twinkling Watermelon begins, and the result is one of those K-dramas that can make you laugh one moment and feel emotional the next.

The story follows Ha Eun-gyeol, a talented guitarist who grows up in a family of deaf parents and a deaf brother. Music is his passion, but his journey takes an unexpected turn when he travels back to 1995. There, he meets his father as a teenager and becomes involved in the events that will shape his family’s future.

Seol In-ah plays Choi Se-kyung, a talented cellist whose return from overseas changes the lives of the young characters. She also plays On Eun-yoo, a character whose connection to the past adds another interesting layer to the story.

What makes her performance enjoyable is the difference between these characters and the way their stories unfold. She brings elegance, emotion and a little mystery to a drama already filled with memorable personalities.

But the real beauty of Twinkling Watermelon lies in its music, friendships and family relationships. The romance is sweet, the time-travel story keeps things interesting, and the emotional moments feel surprisingly personal.

Why should Seol In-ah fans watch it?

This drama gives fans a chance to see her in a different kind of role. If you enjoy emotional K-dramas with music, young love and unexpected twists, it deserves a place near the top of your list.

My take: Start here if you want a drama that offers more than romance. It has the kind of warmth that stays with you after the final episode.

2. Business Proposal (2022)

Genre: Romantic Comedy, Office Romance
Episodes: 12
Seol In-ah’s Role: Jin Young-seo
Where to Watch: Netflix

For many international viewers, Business Proposal was the drama that made Seol In-ah a familiar face. And honestly, it is easy to understand why.

The story begins when Shin Ha-ri agrees to attend a blind date in place of her wealthy friend. Her plan is simple: scare the man away and return to her normal life. But things go wrong when she discovers that her date is Kang Tae-moo, the CEO of her company.

While the main couple brings plenty of comedy and romantic tension, Seol In-ah’s character adds another reason to keep watching.

She plays Jin Young-seo, a confident and independent woman who wants to make her own decisions. Her romantic relationship with Cha Sung-hoon, played by Kim Min-kyu, becomes one of the drama’s most enjoyable storylines.

Young-seo is outspoken, stylish and refreshingly honest about what she wants. Seol In-ah makes her feel lively without trying too hard, and her scenes have a natural energy that fits the drama perfectly.

The relationship between Young-seo and Sung-hoon also has its own charm. Their story balances funny misunderstandings with sweet romantic moments, making them more than just a side couple.

Why should Seol In-ah fans watch it?

If you love office romances, confident female characters and easy-to-watch comedy, this is an excellent choice. It remains one of the best-known dramas in her career.

My take: Even if you have already watched Business Proposal, revisiting it for Jin Young-seo and her romance is worth your time.

3. Love in Disguise (2026)

Genre: Romance, Thriller
Episodes: 12 planned
Seol In-ah’s Role: Kang Jae-hee
Where To Watch: Prime Video, TVING, Apple TV

Seol In-ah takes on a different challenge in Love in Disguise, a romantic thriller that mixes undercover work, a murder investigation and an unexpected relationship.

She plays Kang Jae-hee, a former special-forces soldier who becomes a detective. When a wealthy business heir named Yoon Yi-jun becomes a murder suspect, Jae-hee goes undercover as a male personal aide to investigate him from close quarters.

Her mission becomes more complicated as she spends time with Yi-jun. He has a difficult personality, and their relationship starts with plenty of tension. But as secrets begin to surface, the distance between them gradually changes.

Unlike her familiar romantic-comedy roles, Jae-hee requires Seol In-ah to bring together physical action, determination and romantic tension. The character is trained to handle dangerous situations, so the story gives the actress opportunities to show a tougher side of her screen presence.

The disguise also creates an unusual situation for the romance. Jae-hee must protect her identity while trying to discover the truth, making her personal feelings another complication in the investigation.

Why should Seol In-ah fans watch it?

It is a strong option for viewers who want to follow her latest work and see her in a role that combines action with romance.

My take: The undercover premise makes this one stand out from her earlier dramas. Since the series is still airing as of October 2026, its final standing among her best performances remains to be seen.

4. Beautiful Love, Wonderful Life (2019–2020)

Genre: Family, Romance, Melodrama
Episodes: 100
Seol In-ah’s Role: Kim Cheong-ah
Where to Watch: Prime Video, Viki, Kocowa

Not every memorable K-drama needs a time-travel twist, a wealthy CEO or a supernatural mystery. Sometimes, an ordinary person’s struggles can be just as engaging.

Beautiful Love, Wonderful Life, also known internationally as Love Is Beautiful, Life Is Wonderful, follows people dealing with family problems, personal disappointments and complicated relationships while trying to find happiness.

Seol In-ah plays Kim Cheong-ah, a young woman who faces difficult experiences but continues trying to build a better future for herself. Her character’s journey explores resilience, personal growth and the challenges of moving forward after painful experiences.

Because this is a long-form family drama, viewers get more time to understand the characters and see how their decisions affect the people around them. The story is less about quick romantic moments and more about the ups and downs of everyday life.

Seol In-ah’s lead role makes this drama especially interesting for fans who want to explore her earlier work. It gives her considerably more room to develop a character over a longer story.

Of course, 100 episodes is a serious commitment. If you prefer short dramas with a quick pace, this may not be the easiest starting point. But if you enjoy family melodramas, the extended format can be part of the appeal.

Why should Seol In-ah fans watch it?

It is a useful choice for anyone who wants to see her in an earlier leading role and explore a more grounded, emotional story.

My take: Choose this one when you are in the mood for a longer drama with family relationships and character development rather than a quick romantic binge.

5. Oh My Ghost Clients (2025)

Genre: Supernatural Comedy, Fantasy, Workplace Drama
Episodes: 10
Seol In-ah’s Role: Na Hee-joo
Where to Watch: Netflix, Viki, Prime Video, Kocowa

What if the people who needed legal help the most were no longer alive? Oh My Ghost Clients turns that idea into a supernatural workplace story with comedy, unusual cases and moments of genuine emotion.

The drama follows labour attorney Noh Mu-jin, who gains the ability to see ghosts. These spirits have unfinished business, and helping them leads him into cases involving workplace problems and people who have struggled to get justice.

Seol In-ah plays Na Hee-joo, a practical and capable member of the team. She helps keep the operation running and brings energy to the group’s unusual work.

Hee-joo is a good fit for this kind of story because she is more grounded than the strange situations around her. As the team encounters new problems, her presence helps balance the supernatural comedy with the more serious issues at the heart of the cases.

The series also offers something different from a typical romance. Instead of focusing on a single couple, it combines ghostly encounters with stories about ordinary people and the unfair treatment they may face.

Seol In-ah’s role gives fans another chance to see her in an energetic character who can handle more than romantic misunderstandings.
