Choi Youngjae has always been a shy and timid kitten. When he was 4 years old his mother never came and picked him up from daycare stating that she never wanted a half breed child. Youngjae was adopted into a family that had 2 sons, one was full human and the other was a half breed like himself. What will happen when he goes to school for the first time? Will anyone want a half breed as a friend?
