I'm not sure exactly as I haven't read the novel. But usually in a novel titled like this, there is likely a protagonist who is striving towards a goal. It could be an athlete, a student, or someone in a competitive field.
The main theme could be about perseverance. In many novels with such a title, the characters often face numerous challenges and they have to keep going, showing that they have the heart of a champion, which is the will to succeed no matter what.
Hehehe, I personally think that the 'Heart of a Champion' is a good sports-football novel! The novel described Mr. Zhou's "popularity" in football. He believed that only football had more than three minutes of popularity, which was the key to his success. Not only did the novel have an intense and exciting football game, but it also had the inspirational elements of the protagonist persisting in his dreams and pursuing success. It was very worth reading! I hope you like this fairy's recommendation. Muah ~😗
