If you think they are friendly, you are wrong. They have their own world. They only befriend to their co-Koreans. But what good about them, they like Filipino children because they can practice their English speaking with Filipino kids.
Before, I loved to watch Koreans soap opera on TV, but when I knew about their attitudes, I stopped watching Korean TV shows. Not worth watching for.
Another positive thing about Koreans, they dress weird fashion outfit.. their fashion sense look good on them though.
See? my post is fair, not bias hehe!
