I'm not sure who Amelia and Eleanor are in this story without reading it. They could be friends, sisters, or just two people who happen to go on a ride together.
Alvin often expresses love through grand gestures. For example, he might plan a big concert just for the one he loves, using his charm and star - like quality to show his affection.
One idea could be a story about the chipmunks getting lost in a big city during a concert tour. They have to use their wits and musical talents to find their way back to Dave. For example, they might perform on the street to earn money for a map or directions.
Eleanor and Park isn't historical fiction. It focuses on the present-day experiences and relationships of the main characters, without delving into historical events or periods.
At the beginning, Eleanor is a rigid character with set routines. As the story unfolds, her relationship with Raymond and her own experiences gradually break down her walls. She begins to face her past traumas and in doing so, becomes more confident and self - aware. For instance, she starts to take better care of her appearance and interact more with people in a positive way. This development is slow but steady throughout the novel.
The 'Alvin and the Chipmunks' series has always been centered around the cute and mischievous chipmunks and their experiences like dealing with school, music competitions, and family life. There's no indication of gay storylines. It's a story that aims to appeal to a wide audience including children, and such themes are not part of its narrative.
Dave is a favorite too. His role as a sort of father figure to the chipmunks is heartwarming. In fanfics, his patience and love for the chipmunks are often explored in more depth, especially when they get into really difficult situations and he has to be there to support them.
One idea could be a crossover with the Smurfs. Alvin and the Chipmunks could accidentally wander into the Smurf village while on an adventure in the forest. They might initially be seen as strange little creatures by the Smurfs, but then they team up to save the village from Gargamel who has a new plan that involves using the Chipmunks' musical talents to lure the Smurfs.
