According to the elders, the emotional changes between the brothers Gu Mo and Gu Chi are quite noticeable.
Gu Mo was a renowned child prodigy, skipping grades in school, and although there wasn't a large age gap between him and his younger brother, they never experienced going to and from school together.
The subjects Gu Mo studied were not interesting to Gu Chi.
In contrast, Gu Chi barely scored in the middle range and couldn't get into a good school, later taking the path of an art student. At that time, the brothers rarely communicated, especially when Gu Chi first entered high school; he was a cold, aloof school idol, and he wore a stern face even at home.
