Sinfest isn't a hate comic. It might have controversial elements, but that doesn't make it fall into the category of a hate comic. Different people might interpret it differently, but the general consensus is that it's not about hate.
I'm not sure. Sometimes stories like this are inspired by real-life but are embellished or changed to make them more engaging. It could be a mix of truth and imagination.
In Naruto fanfics, Naruto's hate could be explored in various ways. Maybe it stems from the discrimination he faced as a Jinchuriki. People in the village often shunned him, which could lead to a deep - seated sense of hatred. This hatred might not be a traditional, all - consuming rage, but more of a simmering resentment towards those who made his life difficult.
It could be that Naruto hated fanfiction because it can sometimes create false expectations among the fans. His real story is about hard work, friendship, and perseverance. But fanfiction might focus on other aspects like shipping him with random characters in a way that doesn't fit his true nature. Also, he might see it as an intrusion into his personal story that he and his friends have worked so hard to build in the original series.
Among all the plots in these novels, the character I hate the most is the male protagonist in the Manual of Integrated Traditional Chinese and Western Medicine. He always thinks that Chinese medicine is a liar, which makes me speechless. However, the female protagonist of this book is very interesting. I strongly recommend it to you ~ I hope you like this fairy's recommendation.
Perhaps the development of the characters felt forced or the overall storyline was too predictable. Maybe there was a lack of depth or complexity that you look for in a manhwa.
