Princess Silver (2019)

This drama also features a complex, slow-burn romance where the leads have to navigate their responsibilities in a politically charged atmosphere, just like in Legend of Shen Li.

Key Points: Political intrigue, strong female lead, devoted love, and responsibilities.

Both dramas have strong, smart FLs who find themselves being manipulated and still manage to outsmart all those who are trying to use them. Both dramas involve complicated political schemes and relationships, with multiple layers of hidden identities.
Princess sliver is longer and much more serious, while Fake Princess is shorter, lighter and more humorous, especially in the first episodes.

- reverse harem,
- one of ML's is obsessed with FL (more or less),
- one of ML's wants to gain power and uses FL,
- smart and capable FL,
- politics,
- poisoning

Both dramas feature a FL and ML that have an arranged marriage, before meeting face to face they both refuse to get married, ending up with one of the leads marrying another (In TLOJY the ML marries her sister and in PS the FL marries a general).
But the two fated leads later meet and begin to fall in love without knowing the others true identity, in these parts of the dramas the FLs conceal their identities (In TLOJY the ML also hides his identity though).
Once the couple realizes their lovers true identities and their true feelings for each other they go through a lot of struggles so that they can marry each other, after a lot of failures they finally have their happy ending :)

- multiple opposing males fall for FL;
- FL has amnesia and hidden identity;
- two kingdoms;
- power struggle

Spoiler alert:





Both female leads are princess’s
Both male lead is prince
Both plot talks about amnesia
Both dramas give off a similar vibe

Both FLs grow up as sweethearts with a man who to protect them wipes their memories and sends them to marry another man, continuing to support them from the background. In PS the FL ultimately falls in love with someone else, in TLLTM she returns to him. Both dramas have palace scheming.

Both dramas are driven by the female lead who is forced into an arranged marriage between two royal families. She marries someone who is not the love of her life for the sake of her kingdom. The love of her life patiently waits for a chance to redeem that love.

Both are palace dramas with love squares. 3 powerful men love one woman. A lot of twists and turns and a lot of angst. But very well-written story and great acting in my opinion.

Both SMLs are morally gray and were in love with the FL since childhood but end up marrying her to the ML for personal reasons. Both FLs struggle with trusting the ML, and at one point stab him. Both dramas are historical and have a similar tone and pacing.

Both main male leaders give the same sensation, starting from facial expression, calm spirit, arranged every step, etc.
Female leaders are both quick-witted, clever and kind.
You can see both of them standing equally next to each other without overpowering each other.
Together they just look irresistible and satisfactory.

both dramas FL is smart enough to deal with political issues and warrior/fighter when needed , she is center of attraction of all ML in not only romance for strategies issue also , she faces amenesia

princess agent is by far better than anything else

Although the plot isn't similar there are some parts of the song of glory (from the 18 eps that I've watched so far) that are similar to princess silver:

- Strong female lead

- FL who goes undercover and assumes a new identity to investigate the truth about the situations that they've found themself in.

- both leads fall in love while not knowing each other's true identity

- both fl get caught between a political war
