Another possible theme is the exploration of the unknown. The boy next door might be somewhat of an enigma at first, and the main character's journey to understand him represents the exploration of the unknown. This theme could also be related to the idea of stepping out of one's comfort zone and experiencing new things.
Another theme could be self - discovery. As the story progresses with the presence of this special boy next door, the main character might start to learn more about themselves, their desires and what they truly want in life. This could be related to how they interact with the boy and the situations that unfold.
Growth and self - discovery also play a role. The experiences with the boy next door can push the main character to learn more about themselves, their likes and dislikes, and how to handle relationships. For example, through misunderstandings or shared adventures with the boy next door, the main character might grow as a person.
It could be about friendship or a budding romance. Since it's about the boy next door, it might center around the relationship that develops between the protagonist and this neighbor boy.
The main plot likely revolves around the relationship between Lola and the boy next door. There could be elements of friendship turning into romance, or they might face various challenges together that test their bond.
Love might be one of the main themes. Often in novels with a title like this, there's a relationship aspect that involves love in some form, whether it's romantic love or platonic love between characters.
Friendship could also be an important theme. The characters might develop strong friendships within the neighborhood, which add depth to the story. For example, the boys in the story could be friends and support each other through various situations.
The main characters are obviously Lola and the boy next door. But there might be other supporting characters like Lola's friends or family members who play important roles in the story.
Love could be a theme. Maybe the flower boy next door is the object of someone's affection, and the story explores the development of that love. Another theme could be self - discovery. As the story unfolds, the flower boy himself might discover new things about his identity or purpose in life.
One common theme is proximity. Since they are neighbors, the closeness in location plays a big role in the relationship development. They might start with simple exchanges like borrowing a cup of sugar and it evolves into something more.
Love, obviously. It's in the title. The love between a human and a ghost.
