Another good one is 'Our Unspoken Bond'. It focuses on the unspoken connection between Kanda Yuu and the reader. The story progresses at a nice pace, with the author gradually building up the relationship through small, meaningful interactions.
It's also appealing because it gives fans the opportunity to expand on the existing story. Since the fanfic can take the characters in new directions, readers can experience different scenarios involving Kanda Yuu. For example, some fanfics might explore a more romantic side of him that isn't fully shown in the original work. And the idea of being the one to break through his cold exterior is very alluring for many fans.
Some fanfiction platforms have ranking systems or user reviews. So, look for those features on the platforms where you search for fanfictions. Maybe start with the ones that have high ratings and positive reviews. Also, you could join fan communities dedicated to the relevant fandom and ask for recommendations there. They might be able to point you to some great Kanda Yuu x Reader Lemon fanfictions.
When it comes to writing the lemon part, if you choose to include it, be tasteful. Focus on the emotions and the relationship between the characters rather than just the physical aspect. Use descriptive language to set the mood. Also, make sure to follow the rules of the platform where you plan to post your fanfiction, as some platforms have restrictions on adult content.
Another reason is that the 'Haikyuu' world has a lot of elements that can be used in fanfiction. For example, the volleyball aspect can be incorporated in different ways to show how Nishinoya and Asahi's relationship affects their performance on the court or vice versa. There are also other characters in the series that can be added to the stories to create more complex and interesting plots. All these factors combined make 'Haikyuu Nishinoya x Asahi Fanfiction' quite popular.
Nishinoya doesn't die. The manga continues with him as an active and important character, contributing to the storyline in various ways without facing the fate of death.
A popular fanfic in this pairing is 'Shinoa's Perspective on Yuu'. In this story, it's told from Shinoa's point of view, which gives a deeper understanding of her feelings for Yuu. It shows her internal struggles as she tries to come to terms with her growing affection while also dealing with the chaos around them.
I'm not sure specifically about Mika x Yuu mpreg fanfiction. You could try searching on some popular fanfiction websites like Archive of Our Own. They have a large collection of various fanfictions, but it may or may not have exactly what you're looking for.
One great kimizuki x yuu fanfiction could be one where they go on an adventure together in a magical realm. It might explore their relationship development as they face various challenges.
