One common theme is competition. Just like in the Naruto series where characters compete in ninja battles, in these fanfictions they compete in Guitar Hero contests. Another theme is self - discovery. Naruto might discover a new side of himself through playing Guitar Hero. For example, he could find that he has a natural talent for music.
One popular Naruto Guitar Hero fanfiction could be 'Naruto's Rockstar Adventure in Guitar Hero World'. It might have Naruto using his ninja skills in the context of the Guitar Hero game, like using his speed to hit the notes faster. Another could be 'Team 7 and the Guitar Hero Challenge' where Sasuke, Naruto, and Sakura compete in a Guitar Hero tournament within the Naruto universe.
A major theme is definitely the conflict between desire and commitment. The hero desires someone else, at least momentarily, but he has a commitment to the heroine. This conflict creates a lot of internal and external turmoil in the story. Also, forgiveness is a theme. If the heroine finds out about the near - cheating, she has to decide whether to forgive the hero or not. This theme explores the depth of their relationship and the power of love.
When the hero cheats on the heroine in romance novels, it's a major plot twist. It could cause the heroine to question her self-worth or make the hero realize his mistake and try to win her back. Sometimes it leads to a newfound depth in their relationship, and other times it's the end of it all.
Guitars are very common in pop music, so there are many guitar books. Some popular guitar players and music producers would also write guitar guides on guitar techniques and pop music styles. You can find these books in your local bookstore or online bookstore.
Well, it can have a devastating impact. The heroine might feel betrayed and lose faith in love. It could also lead to a lot of drama and inner conflict for both characters as they try to figure out if they can move past it.
Well, usually these novels have a lot of drama and emotional turmoil. The endings can vary. Sometimes the couple works through it and stays together, sometimes they split up for good.
