Ashes to crown has only started airing when writing this, but doesn't matter because this rec is for the similarities you might enjoy considering the FLs/MLs:

The FLs start out in politically weak positions, but are thrown into court & palace intrigue and have to learn how to survive these situations and secure their positions and gain some actual power instead of being others' puppets. Both FLs also have some revenge aspects in their plans.
Women empowerment aspects :)

Both shows play into some role-reversal aspects considering that the FL ends up in a politically more powerful position and ML is a devoted supporter (though with some antagonistic phases/starts from ML).

Both MLs have hidden identities, know martial arts and grew up surviving abusive 'families' and their schemes.

a) Dominion and Devotion:
FL is hiding her gender and grew up crossdressed as the 5. prince. after the king's death she is used as puppet-emperor by a powerful political faction and has to survive their schemes and establish herself as actual regent with support in the court.
ML is growing up hidden as eunich in the palace, having to survive his own share of being used by others for their schemes but also being among the ones using the FL at the start.

b) Ashes to Crown:
FL grew up as general's daughter in the desert region away from the capital, but is drawn to the capital due to stories about her dead mum and also her first love, a noble with ambitions.
After some betrayel she becomes the Grand Princess to protect the child-empo
eror and has to survive schemes against her & the young emperor, trying to establish her own political support system & power.
ML hiding his identity was part of FL's dad's army and is tasked with protecting her, which he does in his own sometimes antagonistic way.
FL makes him leader of the imperial guard to keep him close and try to win his absolute support against the palace intrigues.

Both shows are set in 20th century, with Mr. Sunshine being set majorly in years 1902-1910 and WOF is set in 1930s, and both showcase a complex time period with Japanese occupation and changing times.

Another major similarity is strong female characters, and the female leads are particularly similar. Both female leads belong to a high status and rich family but both of them are secretly fighting for their nation. In both shows, the female leads have the strongest faith.

Star in My Heart (1997) and Lovely Runner (2024) share a striking narrative foundation that bridges two entirely different eras of Korean television by focusing on the intense, barrier-breaking romance between a superstar musician and an ordinary woman. At the center of both dramas is a male lead—Kang Min and Ryu Sun-jae, respectively—who navigates a high-pressure entertainment industry while harboring deep personal trauma, yet willingly throws away his top-tier celebrity status, agency boundaries, and public image out of absolute devotion to his first love. This shared dynamic blurs the lines between fiction and reality, as the iconic emotional ballads performed by the characters on-screen—Kang Min’s rock ballad "Forever" and Eclipse's viral hit "Sudden Shower"—both crossed over into the real world to dominate domestic and global music charts. Furthermore, both narratives thrive on the immense societal and industrial gap between the leads; whether it is a wealthy 1990s pop star fiercely protecting a struggling, orphaned fashion designer or a modern-day top idol altering timelines to save his most passionate fan, both stories capture the public's imagination by showing a larger-than-life idol who treats an ordinary girl as his entire universe.

A sudden explosion which killed a wealthy Hong Kong businessman has drawn the wrestle between drug traffickers and those against drugs. The heir of the drug trafficking syndicate does not hesitate to create social chaos, with his sole reason for believing in "a world without drugs", which is actually more terrible and more chaotic than imagined.

both feature idols and the complications being an idol brings when it comes to personal relationships

The series The Next Prince presents a royal-themed genre with a concept that feels incredibly epic, grand, and expensive. Visually, it is almost in line with the concept of The Edge of the Horizon, which also carries a royal atmosphere. The luxurious quality of TNP is clearly reflected in its detailed set design, strong cast, and elegant costumes. Every element makes the series look classy, lavish, and highly refined. Overall, this series is highly recommended to watch and definitely worth seeing.

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.

Though Youn's Stay is more on the calmer side, the vibe is very similar.
Normal people are away from their daily struggles to experience a once-in-a-lifetime opportunity.
Full of wholesome moments.
