What I love the most is writing and reading about the side pairings in fanfictions. Because while you know their romance is not the focus of the story, as the author or for the author, their fluff is too strong not to be injected to the story. And i love how the side pairings are not always used just a side attraction but a way for the main pairing in the story to get together at last. My favorite side pairing of all is Daisuga. Seriously. They're like the mature couple slash pair couple counselor that no one asks for but needs to. I also like Kagakuro as a side pairing since they're the most solid couple of all KnB pairings. Not all of you may know them, but I also like the side pairing of Taira and Saku in Beck. That's why their relationship is the biggest model for Ryusuke and Koyuki in my fanfic right now. It's called Omega Note btw and can be found here. https://www.fanfiction.net/s/11982287/1/Omega-Note Please give it a read if you wish.
