The same actor plays similar personages: the CEO's at their own companies and winning at their carrier, losers at their love life... picky about everything. They are more than 10 years older than the female lead with which their work-related life collides at first. They move to live at same building as the female lead, which is a troublemaker. y At first they are very reluctant to understand they had fallen in love and are bad at it..., but the actor express it well through his expressions.

Both revolves around people who choose to be the best at housekeeping after their personal life is ruined.

Both contract marriage drama
Both rich workaholic CEO
Both female leads trying to pursue their dreams
Both even have the same second male lead as rival
Very similar feel overall

The main hero is a person who lost his parents as a child. Later in life due to his work-related life a person takes his own life. After that he also loses the only other person he cares about. Losing all hope he moves away, isolates himselfs and works to help people with his regular job, but being his best at it. His interactions with people saves them...
while helping them gives meaning to his life. At first he starts helping the main heroine... their love later on helps him face his own trauma. Both were ones planing suicide and a female figure saved them out of nowhere.
While main hero and heroine try to find their own footing in life again.. we got involved in the stories of the people, surrounding them.
In both the heroine has also lost her mother as a child and was raised by a single father for a long time.

Main hero is more mature and has a tragic story, surrounding his fiancée and their past. Main heroine is a failure at her job, while working hard for it. Both involve her three friends and their live and love stories.

Both shows focus on the main couple. Both ML are stoic at first but is whipped for the cuteness of FL. Both FL are independent and strong-willed. Both shows have so much sweetness overload from the couples.

One is a contract marriage and the other an arranged marriage!

In both dramas the female is a messy woman who lives in a house build and created by her father, whom she lost. She also lost her mother at young age. She has passion and talent for her job, but is lost in there too. Then the male lead enters her house and life and changes them, while living with her.

The male lead is someone who present thoughtfulness for the preparation of helping one customer at a time. The thoughtfulness of his work is similar.

Though both sageuks have different target audiences in mind (they have differences as if you want some smart political talk you should watch Queen Seon Deok rather than Moon Lovers) they have sone similarities:
> lots of male fanservice (hwarangs in Queen Seon Deok, princes in Moon Lovers)
> the female leads love one man first then she turns to love a man with a darker past (plus both men wear black most of the time, I'm talking about Bidam and Wang So, Kim Nam Gil and Lee Joon Gi Yeah!)
>both the second men the female leads love have mothers that are obsesses with power plus those mothers abandoned those sons too
> both evil mothers have other sons they prefer over the son (the men loved by the female leads) they abandoned without realizing that their abandones sons are the smartest and their closest ticket to power

Similarities:
> both sageuk OTPs have great chemistry (lots of OTP moments towards near the end of the drama).
> both couples made so much effort to show how much they love each other and each of them proves how much they love their other half (especially true of the main male lead in Moon Lovers and main female lead in Princess's Man).
> side couples with their own stories (whether happy or sad) that made you care about them.
> lots of tragic events happening which makes or breaks the lead couples
> expect some tragic things happening among family members due to greed by some
> important theme in both dramas: filial piety vs love vs power
Difference:
> Most of the male lead characters in Moon Lovers (the princes) except for Wang So are played by actors in their twenties (when they made the drama), while the male actors in The Princess's Man (the 3 friends whose lives are changed due to events) are played by actors in their thirties (when they made the drama).
> You see a lot of politicking scenes in The Princess's Man while there's not a lot of those in Moon Lovers, more of the political dealings (example: King's dealings with various factions) are merely explained.
> Moon lovers is set in the dawn of Goryeo era while The Princess's Man is set in Joseon.

By the way: The Princess Man > Moon Lovers Scarlet Heart Ryeo for me

Amazing stories with great actors as main couple. Prime Thai BL, well made. Super exciting to watch.
