Bussaba is more about cooking, but both feature food (and the philosophy behind good food) and both have MLs that are distrusted by the FL, with a large, close support cast.

Of course the original should be recommended first. It's not a verbatim remake, and you can appreciate the differences between the two, as well as the different local cuisine.

Chronicle of daily life of the Emperor and government officials in Chinese court system, leaning more towards portraying the historical events, political debates and the rich culture.

a supernatural deity / god meets a human being
deity is "stuck" on earth and human being helps them
both female leads meet the male deities when they were both going through a hard time
cute chemistry !!
doom at your service if very fluffy (romance) while handmade love is very emotional (kinda slice-of-life)

The story about secretly liking someone for a long time and taking care of them is similar in both movies.
The overall feel and setting is the same. School/University.

I watched train first and then the ghost detective. I am surprised that no one thought the two were similar!
1- the lovestory itself. We know the leads love each other but the show does not make them state the obvious. As in they never declare their feelings to one another but we viewers know how much they love each other. In this way the romance is subtle and beautiful. It touches you deeply especially when you see how far the leads are willing to go for each other.
2- in both shows the leads overcome the impossible to be with one another. In train the ML finds the FL in another universe after her death and in the ghost detective the ML comes back as a ghost to the FL (none of these are spoilers)
3- the antagonists were similar too. Their origin stories, their descent to darkness was kinda similar to me and how it all came down to this question they kept asking

If you enjoyed one you will certainly enjoy the other. I know i did

Both drama has
- Older Woman/Younger man
- Office setup
- Boss/employee, superior/subordinate relationship

Older woman/Younger man relation with office(superior/subordinate or boss/employee) setup. Takane no Hana-san is light-hearted though.

Both about high school girls that are abused at home and bullied at school, founding happiness with a mister (older guy) that helps then run away of their miserable lifes.
