No. Given the rather unclear and potentially inappropriate - sounding nature of the term 'light v l sex fanfic', it is not likely to be a common type. Most mainstream fanfic focuses on more positive, plot - driven, and non - explicit themes.
I'm not entirely sure what 'light v l sex fanfic' specifically refers to. 'Fanfic' is short for fan fiction, which is fictional writing by fans based on existing works. But the 'light v l sex' part is rather unclear without more context.
Well, in l x light yaoi fanfic, often there is a sense of tension. Since l and light have a very intense and intellectual battle in the original story, this can be transformed into a different kind of tension in the fanfic - a sexual or romantic tension. The stories may also emphasize the uniqueness of their bond. The writers might create scenarios where their shared experiences and understanding of each other, despite being on opposite sides in the original plot, lead to a deep connection that is expressed in a yaoi - style relationship. Also, the fanfic might use the existing character traits like l's intelligence and light's ambition in new ways to drive the relationship forward.
One common theme is the intellectual battle. Since both Light and L are highly intelligent characters, many fanfics explore their mental duels in different scenarios.
I'm not sure specifically which 'l x light yaoi fanfic' there are. You could try searching on some popular fanfic platforms like Archive of Our Own. There might be a lot of works created by fans there.
Another characteristic is the different interpretations of their personalities. Some fanfictions might emphasize L's quirkiness more or Light's ambition in new ways. For example, there could be a fanfiction where L's love for sweets is tied to his detective work in a unique way. And for Light, his sense of justice or rather his warped view of it could be explored from various angles.
Well, 'l light fanfiction' could be about various things. It might be centered around a character named L and could explore different scenarios or relationships in a fictional world. It could be a creative take on a story that already exists, with L as the main focus.
Definitely not. The relationship between L and Light in the manga was strictly based on their intellectual battles and opposing goals, not any romantic or physical interaction like a kiss.
