Although Densha Otoko is more comedic, Takane no Hana is more serious, due to the overall plot of her family's story of succession and inheritance.

First, both are asadora dramas. They are set during the similar time periods (early 1900s to early 1950s, though Oshin goes on to the 80s). Both FLs are daughters of sharecroppers and the dramas show how harsh that life can be. Hanako to Anne, however, is portrayed more happier than Oshin.

Looking for mature men in love? The Ossan's Love franchise and Old Fashion Cupcake have you covered! Although Old Fashion Cupcake doesn't share Ossan's same laugh-out-loud comedy and slapstick moments, there is a subtle humor to it.

The fields of both dramas are quite different but somehow I find that they resemble each other. You can see how the characters are diligently and delicately doing their work, how long and difficult their journey to create something, how happy they all when their mission's accomplished, and how passionate they are to never stop challenging themselves. Both dramas also show interesting knowledge & technical information on each field which were nicely narrated & combined with the plot. All the characters are very dear & outstanding, their bonds & teamwork are just the best. Both dramas are really worth to watch!

Parallels between My Devine Emissary and Wonderful Fate include:
The female lead is a student who is struggling academically and is reluctant to take her tests.
She travels back in time and/or into a historical narrative, where she encounters the ML, the emperor.
The connection between the leads in both dramas is that the leads characters are quite similar in that they initially despise one another before becoming friends.

This is a Chinese BL (which was cancelled so last episodes aren't available) and has a novel
This also has non blood related brothers' love trope
I also think this drama portraits a realistic poor environment just like Unknown
Also this drama has one sided obsessive lover too

My Debine Emissary is the Chinese version of Splash Splash Love.
It's a remarke version, from the outfit the female lead wore before travel to the setting, in episode one is the same.
Yes in the chinese version we can see a full on fall out between the mom and the daughter and we had a little flash back to see the father instead of just a picture

CEO power struggle, similar family dynamics, amnesia, love triangle, wife of CEO kills him to take over company, etc etc.
