To put it simply, an otaku traveled to the world of an online novel and became the protagonist in the novel who traveled to another world.
... This statement is really inexplicably bad.
But after all, the otaku is not the male protagonist in the novel. Every move, every move, every smile (mistake) is different from the original protagonist, so the article... Changed from a BG harem to a BL single CP.
A butterfly in the Amazon rainforest in South America, flapping its wings occasionally, can cause a tornado in Texas two weeks later.
The above content is taken from Baidu Encyclopedia.
In short, it just depends on how muddy the male protagonist will muddy the water.
Unscrupulous authors start writing casually based on their emotions, so the possibility of being fooled is very high.
PS. Although I personally don't have CP mysophobia, I like 1vs1... So there will be no studs.
