Sure. 'A Court of Thorns and Roses' has a similar allure with its complex characters and richly built fantasy world. It also features a strong romantic sub - plot like 'Neon Gods Novel'.
The intense emotions, unexpected twists, and passionate encounters make a love story spicy. Maybe it's the forbidden aspect or the high stakes involved.
Well, in kurapika and neon fanfiction, a common theme could be the contrast in their worlds. Kurapika is from a tragic background with his clan's destruction driving him. Neon, on the other hand, is a part of a wealthy and powerful family. Fanfic writers may play with the idea of how these two from such different walks of life come to understand each other. Maybe Kurapika sees in Neon a glimmer of innocence that he wants to protect, or Neon could be intrigued by Kurapika's mystery and strength.
