Chae-Yun is one of the students in the Squirrel class (Korean 6 year old... meaning 4 or 5 in normal age). She is soooo cute, and very sweet. She is one of the students that actually pays attention (well... most of the time, anyway). When she sees me in the hall, she always follows me around (like many of the students do). (Her teeth do need some work, though.) He is in the Hippo Class (the younger of the Korean 5 year olds... basically all of them are 3).
