In the original text, the heroine has a powerful golden finger and many suitors, but the man who is most likely to be the hero in the text ends up with the heroine. The original brother blocked the enemy's blow for the heroine. He was seriously injured and could not recover, and the path to advancement was terminated. The original owner Lin Nannan only appears once in the whole text, and it was in his brother's memories before his death.
As a book wearer, hugging your thighs is a good choice. So between making friends with the protagonist or becoming his enemy, Lin Nannan chose to make friends with him.
Finally... She returned home, and the story was just a story after all.
