In the years of youth, there were originally some steps that had to be built with understanding, tolerance, and sincerity. Each step was a ladder of growth.
Time will settle the truest feelings; Wind and rain will test the warmest companionship. What went far was just a fleeting cloud, and what was left was a love that was worth cherishing. A passionate love may not last long, and a plain love may not be heartless.

In gon and pitou lemon fanfic, Gon could be depicted as being in a complex emotional state when it comes to Pitou. Maybe he's conflicted between his hatred for what Pitou has done and an unexpected attraction. Pitou, on the other hand, might be presented as having a deeper understanding of Gon than in the original story, which leads to some rather unorthodox interactions between them. However, it's important to note that these are often extreme interpretations in lemon fanfics and not necessarily in line with the overall tone of the original series.
It's hard to pinpoint exactly where Gon is in the manga at any given moment. It all depends on the current events and his adventures. He could be in a forest, a town, or some other setting relevant to the story's progression.
