i’m convinced that gayoung has an inferiority complex towards bitna. my theory was that in the past, bitna always got praise and attention for her outstanding art skills. gayoung was in the same class as her and she also drew well, but due to bitna getting all the attention she was overlooked by her classmates and teacher. she then started comparing herself to bitna a lot and getting jealous of her. and thus, she probably turned the other girls in their class against bitna, causing bitna to be the person she is now.
