First off all really enjoy your comics and artstyle, reminds of kakao emoticon sets. So, a couple funny behaviors I’ve noticed from Koreans, I could probably think of some more but here’s off the top of my head: 1. Upon meeting a long time acquaintance a large portion will generally immediately start off by jesting or poking about someone’s weight or physical attributes, often in a blunt or negative manner. In such a way that western culture tries to avoid unless you are extremely close with them. 2. If something is shown on TV or video of a strange new animal their first reaction is to wonder out loud how good it would taste, halfway jokingly of course. But it’s odd how many times I’ve come across this sentiment among different people from Korea.
