In fanfiction, the relationship between Yui and Ruki can be complex. Ruki often has a dominant personality. He might be seen as initially cold towards Yui but gradually developing deeper feelings. In some fanfictions, Yui's innocence acts as a contrast to Ruki's more calculating nature, leading to interesting interactions.
Well, perhaps in the fanfiction, Yui discovers she's pregnant and is filled with a range of emotions from joy to fear. Ayato, on the other hand, is excited in his own way as it's a sign of his dominance over Yui. The story could then focus on how they navigate the changes in their relationship, like Ayato having to be more responsible and Yui having to deal with the physical and emotional changes of pregnancy while living among vampires.
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.
It would likely create a lot of chaos. The vampires are used to having control over Yui, but a pregnancy would shift the power dynamics. Yui would have a new focus - her unborn child - which could make her more assertive. The vampires would either have to adapt or try to regain control. For example, if one of them is the father, he might become more possessive, while the others could be jealous or feel left out.
One possible storyline could be that Yui discovers she's pregnant and has to deal with the mixed reactions of the Diabolik Lovers boys. Some might be possessive and overprotective, while others could be more indifferent or even see it as a way to further manipulate her. The pregnancy could also bring out a more vulnerable side of Yui as she faces the uncertainties of motherhood in such a strange and often hostile environment.
Fanfiction often delves into the psychological aspects of their relationship. Ruki has his own past traumas that shape his behavior towards Yui. Yui, on the other hand, is in a strange new world with vampires. Their relationship development can be a journey of self - discovery for both. They learn about themselves through their interactions with each other. In many fanfictions, this exploration of their inner selves while being in a relationship is what draws readers in.
Sure is. Diabolik Lovers originated as a manga and has since expanded into various forms of media. The manga showcases a unique and captivating storyline.
