Charly is one of the well known youtubers in Korea. She is actually from America and traveled to South Korea to learn the langauge as well as teach English. She is in the TaLK program (she insipired my dreams and is my role model if you wanna call it that) and teaches at a some what small school. She has been in Korea for a year atleast (I think). But please check out her channel: http://youtube.com/charlycheer

She isnt just useful if you like Korea. She also can speak pretty fluent Spanish and knowns American Sign Language. Her videos are fun and random but also informative when it comes to culture or questions about something in Korea. You can also participate in contest that are held quite frequently. So please give her a chance. You will love her I am sure!
