Was there a novel in which the main character and his sister both had high intelligence, and the main character might have a sister complex or a potential sister complex?
Yes, I can recommend two novels to you: My Sister Is Not Honest and The Daily Life of the Demon King After His Rebirth. " My Little Sister Is Not Honest " was a light novel, a fantasy novel. It was about a brother who had a serious sis-con and his little sister who had spent 13 seasons together. Although the little sister was unwilling to tell the truth to the brother, the brother knew the little thoughts of the little sister like the back of his hand. " The Daily Life of the Demon King After Rebirth " was also a light novel, a fantasy novel. It told the story of a character called the Supreme Demon King who was reborn into a modern magic society and became a useless high school student without magic power. He also had a super cute sister, who was also the story of the demon king's doting sister after his rebirth. Although these two novels are of different types, they are both novels that you need the protagonist and his sister to be highly intelligent. The protagonist is also a sister-con or a potential sister-con. I hope you like this fairy's recommendation.😗
