Historic Drama - happy ending

I am looking for historic dramas not mythic (ancient gods etc...) that have a happy ending for the mains.  I am okay if it has tragedy.  I couldn't finish Under Power for many many hours because how cruely  the ML was in the breakup.  I'm okay with a temporary breakup but not when one of the leads is exceptionally harsh with the breakup.   No slapstick comedy but humor is welcome.

Do not want

Time travel

Transmigration

BL/GL (no offence but its not my cup of tea)

FMF love triangle

Okay to have

Slow burns 

Forced/arranged relationship/marriage

Secret identity

Sad event as long as the mains are together and happy at the end

MFM triangle

Crime 

War

Must have

Happy Ending for both mains.

• Sound of the Desert
• Sungkyunkwan Scandal
• The Story of Ming Lan
• The King's Affection
• Zhang Gong Zhu Zai Shang
• Story of Yanxi Palace
• The King in Love

Oops! The King Is In Love (2020)

The Tale of Nokdu

Who Rules the World (2022)

Prince of Lanling (2013) may not have a happy ending, but one can see it as a prophecy in the drama that comes true.. it is the first cdrama that intrigued and touched me

Prince of Lanling (2013) may not have a happy ending, but one can see it as a prophecy in the drama that comes true.. it is the first cdrama that intrigued and touched me

Thanks for the advise about Prince of Lanling but that is a big NO.  My first taste of k/C -dramas was Mr. Sunshine.  I was so depressed and cried so hard after watching it I promised myself I would only watch happy endings.  

 AuntJoy:

I'm trying out Yanix Palace but wow 70 episodes and at episode 6 and the mains have not even met yet.

Just an FYI - the mains get a happy ending but the story lines for the very likeable SML and SFL are quite tragic.

 AH :

• Sound of the Desert
• Sungkyunkwan Scandal
• The Story of Ming Lan
• The King's Affection
• Zhang Gong Zhu Zai Shang
• Story of Yanxi Palace
• The King in Love

The king in Love, to me, was not a happy ending.

 Stephenia:

The king in Love, to me, was not a happy ending.

For almost all of the dramas I listed, there is a relatively likeable SML who does not get a happy ending. But that's a pretty typical fate for a SML (especially in a historical romance drama setting) and AuntJoy specifically asked for a happy ending for the mains. 

For The King in Love, even though the circumstances were not ideal and the leads were obviously sad about leaving the SML behind, I consider it a happy ending for them because both leads survived, they got to end up together and the SML willingly sent them off.
