Where to Watch My Dearest Nemesis

Is My Dearest Nemesis on Netflix?

As of May 2025, My Dearest Nemesis is not confirmed to be on Netflix. The primary streaming home for international audiences is Rakuten Viki, where the full series is available with English subtitles (Viki). In South Korea, the series aired on tvN in the Monday-Tuesday 20:50 slot (AsianWiki).

Other streaming platforms for My Dearest Nemesis

Besides Viki, the show appears on Apple TV’s storefront as a listed title for purchase or rental in the United States (Apple TV). JustWatch confirms that in the U.S., Viki carries the series both free with ads and through a subscription (JustWatch). No major announcements have been made about Disney+ or Amazon Prime Video.

The implication: My Dearest Nemesis has a narrower reach than flagship K-dramas. Enthusiasts who already use Viki will find it easily; those waiting for a Netflix drop may be waiting indefinitely.

Is My Dearest Nemesis Worth Watching?

Is My Dearest Nemesis hit or flop?

It’s too early for an official verdict. No professional review aggregation (like Rotten Tomatoes) exists for the show yet. Early audience comments on MyDramaList are mixed: some praise the leads’ chemistry, others find the plot predictable. The series has not been declared a hit or flop by any official source.

Audience reception and ratings

Mun Ka Young and Choi Hyun Wook are generally praised for their performances — the “enemies to lovers” transition is the strongest element according to early reviews. However, the webtoon adaptation faced the usual challenge of satisfying existing readers. Ratings data from Nielsen Korea for the tvN broadcast is not publicly available in our research.

Why this matters: for K-drama fans who prioritize chemistry over plot novelty, My Dearest Nemesis delivers. But if you value high-stakes drama or nuanced storytelling, the series may feel like a comfortable but familiar ride.

Ending of My Dearest Nemesis: Happy or Sad?

Is My Dearest Nemesis happy or sad ending?

Spoiler-free: the ending is reportedly happy for the main couple. Baek Su-Jeong and Ban Ju-Yeon reconcile their past and build a relationship, consistent with the romantic comedy genre. Because the show completed its 12-episode run on March 24, 2025 (AsianWiki), any “ending” discussion refers to the fully aired finale.

Do Su-Jeong and Ju-Yeon get together?

Yes. The plot arc — a workplace reunion after a 16-year online-game crush — leads to a resolution where the two leads overcome misunderstandings. The final episode reportedly wraps up their relationship on a positive note. The webtoon ending may differ, but the drama takes its own creative liberties.

The trade-off: fans of the webtoon should approach the drama as a separate adaptation. If you’re looking for a feel-good conclusion, the series delivers.

Plot and Cast of My Dearest Nemesis

What is the plot of My Dearest Nemesis?

Baek Su-Jeong (Mun Ka Young), a planning team leader at Yongsung Department Store, meets her new boss Ban Ju-Yeon (Choi Hyun Wook), the director of strategic planning. She soon realizes he is the same person she met 16 years earlier in an online game — her first love and, apparently, her nemesis. The series follows their rocky workplace dynamic as old feelings resurface (Apple TV).

Who are the main cast?

• Mun Ka Young as Baek Su-Jeong
• Choi Hyun Wook as Ban Ju-Yeon
• Supporting cast includes department store staff (names not widely confirmed in research)

The pattern: the “enemies to lovers” formula gets a tech-friendly twist — instead of a childhood betrothal, the history is forged in an online game. That angle makes the reunion feel modern and relatable for viewers who grew up in online communities.

My Dearest Nemesis Episodes and Webtoon Origin

How many episodes does My Dearest Nemesis have?

The series is listed as 12 episodes on both AsianWiki and Viki, with a broadcast period from February 17 to March 24, 2025. That’s shorter than the typical 16-episode K-drama format, which may appeal to viewers who prefer tighter storytelling.

Is My Dearest Nemesis based on a webtoon?

Yes. It is adapted from the webtoon Geunomeun Heukyeomryong (also titled My Dearest Nemesis in English) by Hye Jin-yang. The webtoon was published on Naver from September 23, 1999 to March 8, 2021, according to AsianWiki. (Note: the start date appears unusually early; AsianWiki’s data may need cross-verification).

“My Dearest Nemesis is a South Korean romance-drama television series that premiered on tvN in 2025. It is based on the webcomic ‘Geunomeun Heukyeomryong’ by Hyejinyang.”

— AsianWiki (K-drama database)

“Baek Su Jeong leads a planning team at Yongsung Department Store. She meets her new boss, Ban Ju Yeon, who is her first love from an online game 16 years ago.”

— IMDb (film and TV database)

For international K-drama fans, My Dearest Nemesis offers a satisfying enemies-to-lovers story anchored by strong chemistry, but its limited streaming footprint means you’ll likely need a Viki subscription. The choice is clear: if you’re comfortable with that platform, dive in — otherwise, you may miss one of 2025’s most charmingly predictable rom-coms.
