For Harry, his growth could be shown through how he becomes more open - minded. He starts to embrace Luna's quirks and her different way of seeing things, which in turn makes him more accepting in general. For example, he might initially be a bit hesitant about Luna's belief in some of the more out - there magical creatures, but as they date, he starts to see the beauty in her imagination.
The development could involve them learning to control and understand the soul bond. They might face challenges like other wizards trying to break the bond for their own gain. As they overcome these challenges together, their bond grows stronger. For instance, when they are in a duel against dark wizards who sense their powerful bond and target it, they have to defend it and in the process, become closer.
Harry might become more at peace. After all the battles and losses, he could focus on the positive aspects of life. Luna, on the other hand, could become more confident in sharing her ideas. She no longer has to be in the shadow of the war and can be more outspoken.
To develop their relationship realistically, the author could focus on their individual growth and how they influence each other. For instance, Luna could help Harry to be more open - minded and less focused on the obvious. Harry, in turn, could give Luna a sense of security. They might start by having small gestures like Harry giving Luna a book she's been looking for, and Luna making Harry a special charm. As these interactions increase, so does their romantic relationship.
It could develop as Harry teaches Lily Luna advanced magic. He might start with Patronus magic, and as he guides her through the process, they get to know each other better. Lily Luna, in turn, could share her school experiences with Harry, and they start to understand each other on a deeper level. They might also have some father - daughter disagreements, which they work through, further deepening their relationship.
One idea could be that they bond over their unique experiences with the wizarding world's strange creatures. For example, they might go on a secret mission to find a rare and endangered magical beast, which deepens their relationship.
At the Yule Ball, they could start by sharing a joke about the overly formal atmosphere. This simple moment of connection can be the start of a deeper relationship. As they dance, they might notice little things about each other, like the way Harry's eyes sparkle in the candlelight or how Luna's hair seems to have a life of its own. This mutual admiration can gradually turn into romantic feelings.
You can start by looking on fanfiction websites like FanFiction.net or Archive of Our Own (AO3). On these platforms, you can use the search function and type in 'Harry Potter Luna' to find a wide variety of fanfictions centered around her character. Some fanfictions might explore her relationships, her adventures outside of the main story, or her unique perspective on the wizarding world.
Well, in some fanfictions, Harry might get some pep talk from his friends. For example, Hermione could tell him that Luna is a really nice girl and he should just go for it. This gives him the initial nudge. Then, he might see Luna doing something really cool, like standing up to some bullies or showing off her unique knowledge of magical creatures. That moment could make him think 'She's so amazing, I have to ask her', and finally he just takes a deep breath and does it.
Authors usually portray Luna as the voice of reason. Since she has a very unique perspective on the wizarding world, she often acts as a counterbalance to Dark Harry. For example, when Harry is about to make a rash or cruel decision, Luna will step in and offer a different view. She is also shown as being very empathetic towards Harry, trying to understand the root of his darkness.
The main characters are Harry and Luna. Harry, being the famous Boy Who Lived, brings his experience of fighting dark magic and his Gryffindor courage. Luna, with her dreamy and perceptive nature, offers a different perspective. Their baby is central to the story as it drives the plot, whether it's about protecting the baby, nurturing its magic, or exploring its unique place in the wizarding world. And of course, their friends from Hogwarts play supporting roles, adding more depth and relationships to the story.
