9. My Father Is Strange

10. The Dinner


10 Korean titles in which a character says something like 'we are koreans we do [this]' and says something typical for Koreans

1. Hometown Cha Cha Cha - SML brought Western style breakfast for FL. ML was jealous and said something like "we are Koreans, we eat soup for a breakfast!"

10. Dear my friendsThere are ten of them, this is just a section of the table.

Bonus  :  as this is not Korean, but Chinese drama : Find Yourself, second couple said : We are chinese, every problem can be solved on dining table. 

At this point I'll accept dramas from any country

So, Chinese one from above counts too

3. Creating Destiny - dialogue between leads, something like Koreans should help each other when they are abroad

I know many dramas have this, but cannot recall. 

4. The Package- Has many references to this, as a group of Korean tourists are on a trip to France- one is Koreans must always have rice, then some conversations around soju v/s whiskey, there are comparisons of the tourist places there to those in Korea, how to behave with elders, etc. 

5. Crash landing on you (I can’t recall a specific one but there were many sentences about North Koreans do this, South Koreans do that.. it may fit your trope.)
