My younger brother had already experienced the feeling of being betrayed in high school. I remember at that time, his school collaborated with other schools to organize a long-distance running race. It was a very ordinary competition, where the most one could win was school-wide praise, but to a child at such an impressionable age, this was undoubtedly a very tempting event. Not only would the winner be famous in his own school, but also in the other schools, it was a matter of great honor.
