How can the romance develop between a heroine who is afraid of the hero in a novel?

Maybe the hero has a very strong and intimidating presence. His power, either physical or in terms of status, might be overwhelming to the heroine. For example, if he is a king or a very wealthy nobleman, the heroine, who could be from a lower social class, might be afraid of the power imbalance between them.

The hero might start doing small acts of kindness for the heroine, even if she initially rejects them. Over time, these acts can wear down her defenses. For example, if the heroine loves books and the hero starts leaving rare books for her at her doorstep anonymously. Eventually, she'll start to wonder who is behind it and might soften towards the hero.

Often, at first there is a lot of animosity. The heroine is understandably angry and scared due to being kidnapped. But as the hero shows some kindness or vulnerability, the heroine begins to see him in a different light. For example, he might protect her from other threats while she is in captivity.

The plot could develop as the hero and heroine are forced to spend time together due to some external circumstances. As they interact more, they start to see the good in each other and the hero's hatred gradually fades. For example, they might be working on a project together or be stranded in a place.

Challenges also play a role in developing this dynamic. External factors like family opposition or misunderstandings can test the hero's adoration. But if he overcomes these challenges, it shows the depth of his love for the heroine. For example, if the hero's family doesn't approve of the heroine because of her lower social status, the hero has to fight for their relationship, which in turn strengthens his adoration for her.

One such novel could be 'Dark Desires' where the heroine is initially terrified of the brooding and mysterious hero due to his dangerous reputation.

Most of the time, the hero/heroine is initially repelled by the villain's actions or nature. But then, the villain may show a different side, perhaps a more gentle or understanding side in private. This creates a sort of internal struggle for the hero/heroine. In 'Poison Study' by Maria V. Snyder, Valek is a rather intimidating and morally ambiguous character. Yelena has to work with him and over time, she discovers his loyalty and other positive traits, and their relationship evolves into a romantic one as she peels back the layers of his 'villainous' exterior.

The development can be aided by the heroine's own growth. As she gets to know the hero better, she might realize that his dominance is not all bad. She could start to see it as a form of strength that can be beneficial for them both. And if the hero respects her boundaries and is willing to step back when she's really scared, it can lead to a more positive relationship.

One way is to give her a tragic past. For example, if she has been betrayed or lost someone dear in a cruel way, it could lead her to close off her emotions. This past trauma can be a driving force that makes her reluctant to show or feel emotions in the romantic context of the novel.

The development of their feelings could be quite complex. Maybe they start with indifference or even hostility. But through shared adventures or moments of vulnerability, they could start to see each other in a new light and slowly fall in love against all odds.
