I'm still alive and breathing. And since I wanted to share something and didn't know where exactly to say it I remembered that there was asianfanficas and I returned just so I can write that something and log out again. 

When/If you're watching videos with facts about Korea - only trust 50% if what they tell you. Usually those videos in English are made by people who made a little(definitely not enough) research. 
Like when someone tells you Koreans don't eat dogs....Well some of them still do. But those dog restaurants are hidden and foreigners don't know where exactly to find them. 
Or if you hear that Koreans drink a lot of coffee....don't think that it's anything different than Americano cus they're crazy for Americano.

So yeah...My point is - either watch videos where Koreans tell you what it really is like. Or visit Seoul once...but that might ruin your imagine of Korea.
