I have a little suggestion for one lesson in korean

hi, i’m a korean and I was going through some of the lessons in korean.
Then I found a collection called “김현희의 고백” which is written by Hyun Hee Kim who used to be a north korean spy.
There are some difference in spelling words between South Korea and North Korea. and also some words are different.
I was worried if learners might be confused with the article without knowing the difference, so I hope if there are some sort of footnote-like explanation under the articles.

I thank you for your suggestion, Superlee323. Please note that this collection is placed in the Advanced 2 category. Advanced learners will be well informed of the differences in North Korean and South Korean words and spelling. As such, no footnote is needed.

EDIT:
I’lI tag the collection with “North Korea” and “북한".
