Show their differences and how they complement each other. The female OC might be more bold and outspoken, while Yui is more reserved. The OC can encourage Yui to stand up for herself more, and Yui can teach the OC about the subtleties of dealing with the vampires. Their different personalities can create an interesting dynamic in the fanfic and help develop their relationship.
One idea could be that the female OC is a new student at the school. She has a special power that she doesn't fully understand yet. Yui befriends her, and together they try to figure out the secrets of the Sakamaki brothers. The OC's power might attract the brothers' attention in different ways, some being more menacing and some being more curious.
Communication is key. Yui could start writing letters to Shu, pouring out her thoughts and feelings. Shu, initially hesitant, might start to respond. Through these written exchanges, they could learn more about each other's inner worlds. As they become more comfortable, they could start having face - to - face conversations that are more honest and deep - rooted in their emotions.

In some fanfictions, Yui's innocence acts as a contrast to Ruki's more calculating nature, leading to interesting interactions.
The relationship can be developed through shared experiences. For instance, if they face a common enemy, like a powerful vampire who wants to harm Yui. As they fight together, Subaru realizes how much he cares for Yui and she starts to see a different, more protective side of him.
After the kiss, their relationship could become more intense. Ayato might become more protective of Yui, not wanting any of the other vampires to come near her. Yui could start to feel a deeper connection to Ayato and be more willing to open up to him about her feelings.
Their relationship would become more intense. Ayato would likely be more possessive and protective of Yui. He'd be constantly by her side, fearing for her and the baby's safety. Yui would rely more on Ayato, and their bond would deepen as they face the new challenges together.
In Diabolik Lovers, Yui and Ayato have a complex relationship. Ayato is often possessive towards Yui. Their relationship could develop in many ways in fanfiction. For example, they might start to understand each other's past traumas and grow closer through shared experiences. Maybe Ayato realizes the importance of respecting Yui's feelings rather than just being domineering.
In some fanfictions, Yui develops more agency. Instead of just being a passive victim, she starts to fight back against the vampires in a more strategic way. For instance, she might learn how to use their weaknesses against them.
Ayato would likely become more possessive. Since Yui is carrying his child, he would see her as even more precious and something that belongs solely to him. He might be more affectionate in his own rough way, like constantly checking on her and being more touch - sensitive.
