Communication is key. In the fanfiction, show them having deep conversations about their hopes, dreams, and fears. The male human can share his experiences growing up as a human, and Sunset Shimmer can talk about her life in Equestria and at Canterlot High. This open communication will make their relationship seem more real and believable as it progresses.
One great 'human x sunset shimmer fanfiction' is 'A New Beginning'. It has an interesting plot where the human character helps Sunset Shimmer adjust to a new life in the human world. The relationship development between them is really engaging.
One plot idea could be a male human who discovers Sunset Shimmer's world by accident. Maybe he's a new student at Canterlot High and is immediately drawn to her mysterious aura. He could then help her with some sort of school project that also involves dealing with magic problems in their town.
Show their growth as individuals as well. Maybe the OC is trying to overcome a fear, and Mirajane offers support. This mutual support system is a key part of a realistic relationship. Also, don't rush into the romantic part. Let their friendship develop first. They could share inside jokes, or have a special place in the guild where they always meet. This way, the relationship evolves organically. Another important aspect is conflict. They might have disagreements about how to handle a guild situation, but they work through it, which strengthens their bond.
To develop their relationship realistically, start with small interactions. For example, have them meet at a local coffee shop in Inaba. The male OC could accidentally spill his drink on Rise, and he apologizes profusely. This simple encounter can be the start of them getting to know each other. Then, gradually build on their conversations. Maybe they find out they have common interests like a love for a certain type of music.
To develop their relationship realistically, start with their initial meeting. If the male OC is from a different background, there should be some level of distrust or misunderstanding at first. For example, if he's from a poorer region and she's a Lannister, she may look down on him. As they interact more, small acts of kindness or shared interests can start to break down the barriers. For instance, if they both have a love for a certain type of horse, it can be a starting point. Their relationship should also be affected by the political climate around them. If Cersei's power is threatened, she may be more hesitant to show affection for the male OC for fear of looking weak.
To develop their relationship realistically, start with small interactions. Have them exchange glances, short conversations. Let them gradually learn about each other's likes and dislikes. For example, if Wanda likes a certain type of tea, the male OC could surprise her with it. Then, as they face challenges together, like fighting a common enemy, they start to rely on each other more. Their relationship should grow organically, not too fast.
First, start with small interactions. For example, the male OC could accidentally bump into Alicent in the corridor and exchange a few polite words. Then, gradually increase the frequency of their meetings. Maybe they both have an interest in a particular book in the library and start discussing it. This way, their relationship can build slowly and realistically.
Some dedicated MLP (My Little Pony) fanfiction forums might also have some good 'human x sunset shimmer' stories. These forums often have a community of passionate fans who share their works and recommendations.
Their relationship could develop realistically if Naruto starts by seeing the pain in Kaguya's past. He has a history of empathizing with his enemies, like Nagato. So, he could begin to understand why Kaguya did what she did. This understanding could be the first step in them forming a connection.
It could start with mutual respect. Hollyleaf might admire Willowshine's skills as a medicine cat, and Willowshine could respect Hollyleaf's strength and determination. As they interact more, they start to see the good in each other and slowly become friends, which could potentially develop into something more over time.
