Imagine you are living abroad for a year what about would you miss abroad about Korea?

I often think about living abroad, because I want to study English in abroad. When I imagine I am living abroad for a year, I am always fearful staying with foreigners and not doing things together with my family, friends. And I also miss Korean food. Because I really love Korean traditional food, then when I went Vietnam, the food is not to my taste. I really want to go abroad but when I think like that, living abroad for a year is such a long time to me. I have alternative, that is getting close foreigners and acclimatizing abroad.
