What are the common themes in sibling romance novels?

One common theme is the struggle against society's norms. Since step - sibling relationships are often seen as taboo in society, the characters in these novels usually have to fight against the judgment and expectations of others.

Jealousy is a common theme. Siblings or rival characters in high school novels often feel jealous of each other's achievements, popularity or relationships. For example, if one sibling gets a lead role in a school play, the other might be jealous.

One common theme is loyalty. Siblings in these stories are always loyal to each other, no matter what. For instance, in many fairy tales, when one sibling is in trouble, the others will do whatever it takes to save them. Another theme is growth. They grow together, learning from each other's mistakes and successes. Like in real life, an older sibling might teach the younger one how to ride a bike, and in return, the younger one might show the older one a new way to look at things.

Separation is another one. It could be because of different reasons like family relocation, or one sibling going to a boarding school far away. They might miss each other a great deal and feel lonely without the other around, which is quite sad. For example, I knew of two brothers where one had to move overseas with their father for work reasons. They used to be so close, and after that, they both struggled with the distance.

A common theme is initial conflict. Step siblings often come from different family backgrounds and may feel territorial about their new living situation. For example, they might compete for their parents' attention. Another theme is the journey towards acceptance. As they spend more time together, they start to see each other as family. And also, shared experiences play a big role. Like if they both go through a difficult time at school or in the family, it can bring them closer together.

Common themes could include forbidden love, family secrets, and power struggles within the harem. Tropes might involve rivals for the protagonist's affections and hidden agendas among the siblings. Also, there's often a lot of emotional turmoil and character growth.

The theme of sacrifice is often seen. A sibling might sacrifice their own dreams or opportunities for the sake of the other. And when that sacrifice is not fully understood or appreciated, it can turn into a sad story. Another theme is the loss of innocence. As siblings grow up, they might face harsh realities that change their relationship for the worse, like financial problems in the family that cause stress and strain on their bond.

Family loyalty is also a prevalent theme. Spock is known for his loyalty to his family in the Star Trek series. In fanfiction about his baby sibling, this loyalty is often explored in different ways. He might protect the baby sibling from harm, or he might be involved in teaching the baby about their family heritage and values, whether it's Vulcan or human.

One common theme is competition for parental love and attention. Siblings often feel they need to be the favorite. Another is competition in achievements like in school or sports. For example, in a story, two siblings might fight over who gets the best grades. Also, jealousy is a big theme. When one sibling has something the other wants, like a new toy or a special privilege, it can lead to rivalry.

Well, common themes could include competition for resources or attention, jealousy, and trying to outdo each other.
