They all say that korean artist very handsome and pretty ,so this is one key point but i'm also think like that...I know my classmate wanna learning korean language,they really crazy like koren.most of them say that wana to korean live and some say that korean's food is nice..

Then,got a terrible thing in my class is ,when they talking with each other ,they use korean language...but i'm use mandarin..i'm sit at there was surprised ,i dun understand that what are they talking about ..
Got a friend draw her lovely artist in her book ,not just one drawing ,she draw many in her book?
