Birth secrets,

rising to power,
FL and ML joining forces,
good writing, excitement
historical fictions

Both dramas show the lives of Joseon people during the Japanese colonization.
The struggle against foreign power to protect own's country.
Very intense and interesting dramas

If you are interested in how did Joseon come to that state in Mr. Sunshine, watch Nokdu Flower to know the story.
The events of Japanese colonization start showing in Nokdu Flower and we see how people lived after that in Mr. Sunshine.
What starts in Nokdu Flower continues in Mr.Sunshine as the independence army.
History, rebellion, sacrifice, patriotism, betrayal, and war. All of them are a continuation of each other in these dramas.
The characters in these dramas play similar roles too.
Not to miss if you are interested in the history of that era.
From Nokdu Flower in the 1890s, to Mr. Sunshine in the early 1900s.

Son Sukku looks like Jo Seung Woo (I had to. But it is more than appearances). Both are Gu 'sajangs' with that kind of personality.
The dramas slow vibe, music, directing, etc.
The romantic relationship in My Liberation Notes, and a similar one in Life only it was very subtle.
Following lives of multiple characters.
Greatly written.

The two dramas are very similar. About the relationship of a mother and her three daughters.
The stories of each of the three daughters have many similarities:
- The eldest is married, with one daughters and has struggles in her life.
- The second meets her junior in her company
- The youngest chases a work superior who is older and not welcome by the family’s condition (and in both dramas they were the cutest imo)

Le Se Young’s (actress) characters are very similar in both dramas.
The personality, cuteness, even the cat (“meow”) sound effects and the same camera zoom are there.

Friendly and sweet fun dramas
Bickering old friends that slowly realize their feelings for each other
Great chemistry
A Lovely Light watch

They are all 30 years-old people and the stories surround their work and their friends. Well done heartfelt rom-coms.

Both dramas start with birth secrets; daughters separated from their family from a young age.
Work relationship between rich man and poor woman and disapproving parents, then similar breakups.
FL and ML are somehow related but not related.
Dear Heaven felt 'healthier' to watch. My Glden Life was more melodramatic.

Same writer, same wittiness, same values. There is meaningfulness in every situation.
Same amazing male lead
Both are sweet and very entertaining despite their length. Everything is well paced.
Highly underrated gems

Slow and steady calm dramas
Similar themes with a daughter finding her parents.
Beautiful steady relationship between ML and FL
And you guess it…. The same controversial love between step siblings. But nothing immoral.
Both are great dramas that are worth it.

At first look…
A poor high school girl meets rich guy starting/finishing enlistment.
Death: (Someone is forced to hide the truth about the death of the other’s sibling).
Time jump.
Park Hae Mi in both dramas -I love her.
