I recommend the novel,"I Want to Play Esports, I Hate the Entertainment Industry" to you. The male protagonist was a professional player. He had lost a match in the quarter-finals of the S8 season due to a mistake. Later, he returned to Parallel World and realized that eSports had a very high status. The female lead was a girl who wanted to play e-sports. She later successfully participated in the international competition. The male protagonist had sleep disturbances because he was nervous and had difficulty falling asleep. This is a very interesting esports novel. I recommend you to read it. I hope you like this fairy's recommendation. Muah ~😗
