After learning the simple rules with his dad, Jinyoung also started going to a baduk class. The first time he played baduk with a friend from the class and lost, Jinyoung was really upset. When he played with his dad, it was okay for him to lose because he was an adult... But his friends in the baduk class were already veterans of the class, even though they were younger than Jinyoung. It wasn't easy for Jinyoung to win a game. Still, his friends in the baduk class didn't get angry or throw their stones roughly even when they lost. Even young children tried to control their minds. Jinyoung was upset, but he held it in and came home. In his diary, where he had written a month before about going to Seoul National University, he wrote, "I will definitely become a baduk master."
