My Royal Nemesis

Both have Supernatural (rich?) female leads and Rich male lead.

Both have a strong supernatural female lead. Jang Man-wol (Hotel del Luna) is a centuries-old ghost with a tragic past and Shin Seo-ri is a Joseon-era seductress who possesses an actress in the modern day. Both women are seen as villainous or dangerous but have deep emotional scars underneath.

Both are set in the modern world, but tied to historical past. Man-wol is stuck in the modern era because of her sins from Joseon and Seo-ri’s spirit enters the modern world after her Joseon execution.

In My Sweet Mobster, a CEO/ ex gangster falls for a struggling entertainer. In My Royal Nemesis, a monstrous chaebol falls for a Joseon villainess transported into the body of a struggling actress. Both situations lead to hilarious consequences.

Similar concept but it's more sad in the beginning but with the more emotional intensity, complicated royal relationships, political tension, heartbreak and unforgettable chemistry, then Scarlet Heart: Ryeo is a must watch. It slowly turns into one of the most emotionally devastating historical dramas ever. The relationships between the princes, the betrayals, the longing, the sacrifices and the tragic romance hit really hard. Lee Joon Gi absolutely steals the show as Wang So, and the OST makes every scene feel even more painful in the best way possible. Just prepare yourself emotionally because this drama does not play with your feelings at all.

- both female leads show a big change in personality or behavior
- both male leads are thrown into strange situations because of the female lead
- both stories involve a hidden past or secret heritage driving the plot
- both dramas include the main leads bickering
- both female leads are possessed/cursed by a supernatural being

King/ CEO vs Consort relationship

Consort develops feelings to protect the ML.

Politics, families opposed to the King/CEO follow the same dynamics.

both are:
- Love-hate romances between a clingy but no damsel in distress FL, and an icy on surface but secretly smitten ML.
- Comedies with a lot of heart.

And, both use:
- fantasy elements to highlight real struggles.

A softened devil kind of chaebol slowly heals the emotional traumas of a tragicomical woman who sets out to make a new life for herself in a highly self-aware, hilariously tropey romcom.

Same vibes...
Ancient Magic & Modern Romance... Both shows use a supernatural object or spell from the Joseon era that directly impacts the present-day romance.
Also both have Fated Lovers..., Love-hate relationship, Wealthy man/poor woman

Similarities:
- The ML falls for a strong woman who dislikes him at first.
- The drama is hilarious.

- The cut-throat corporate world as a setting.

- The FL is a strong/ athletic/ dominating woman who comes to rely on the ML.

- Two ambitious people who are initially "enemies", fall for each other.

So Jin Ha, a top medical student, once shared a passionate three-year romance with Cha Seon U, a thug.

Eight years later, Jin Ha is an exceptional surgeon, while Seon U has become a powerful CEO. Fate reunites them when he ends up on her operating table. He risks everything to win her back, while she still struggles with the wound he left behind.

Both series have a very similar premise when it comes to time travel. In both of them, one of the main characters somehow ends up in the future, and the romance gradually develops as they try to understand the world they are now living in and how everything around them works. Although in The King: Eternal Monarch, the story unfolds a bit differently and has its own unique elements and particularities.
______________________________________________________
Ambas series tienen una premisa bastante parecida con respecto a los viajes en el tiempo. En las dos, uno de los protagonistas termina llegando de alguna manera al futuro, y el romance se va desarrollando mientras intenta comprender el mundo en el que está y cómo funciona todo a su alrededor. Aunque en Rey Eterno Monarca la manera en que se desarrolla la historia es un poco distinta y tiene sus propias particularidades.

Both are TIMETRAVEL ROMANCE Kdramas.

My Royal Nemesis mentions Thousands Years of Love in ep 1 (Shaman scene).

For those curious, this is the 1st timetravel kdrama mentioned.

Thousand Years of Love had quite good plot but VERY cheap Costumes etc. So IF you can overlook how Cheap looking it is, it might be decent watch if you enjoy the Timetravel genre.

Both are TIMETRAVEL ROMANCE kdramas,
where one lead timetravels from Past Joseon Era into MODERN DAY.

Both are very funny and recommended for High Entertainment Value.
