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.

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