It could be that the themes and emotions explored in the manga resonated deeply with something personal in your life, making you feel down. Or perhaps the ending was unexpectedly disheartening.
Maybe it had a really sad or tragic storyline that hit you hard.
Maybe it's because the idealized love in them makes you feel your own reality is lacking, or the heartbreaks and complications portrayed are too overwhelming.
Maybe it didn't have a fulfilling ending or the story lacked depth. Sometimes, if the characters' development isn't satisfying, it can leave you with that empty feeling.
Often, they have a gloomy mood. For example, in many such novels, the settings are often dull, like a run - down town or a desolate countryside. The characters usually face difficult situations, such as poverty, loneliness or unrequited love.
We can conclude that the reason why Under One Man's manga stopped updating was because there was a bug in the plot and the plot needed to be re-written. The author, Mi Er, said in the notice that if the plot did not work out, it would need to be delayed. The reason for the halt sparked speculation and discussion among the fans. In addition, there were other possible reasons, such as the author's illness, business, vacation, etc., but the specific reasons were not mentioned in the search results provided.
Maybe the creator ran out of ideas or faced some personal issues that prevented them from continuing.
It's hard to say exactly. It could be that the manga wasn't meeting the expectations of the publisher in terms of quality or market demand. Another possibility is that there were legal or rights-related complications that led to its discontinuation.
The Bleach manga ended possibly due to the author's creative decisions or reaching a natural conclusion for the story.
The HxH manga stopped possibly due to the author's health issues or creative burnout. Sometimes creators need a break or face unforeseen circumstances that prevent them from continuing.
The Berserk manga could have stopped because of a combination of factors. Maybe there were legal issues, or the author decided to move on to other projects. Also, it's possible that the fan response wasn't as expected, influencing the decision to halt the series.
I think it could be due to a variety of reasons. Maybe the manga wasn't getting enough views or there were legal complications. It's hard to say for sure without official info from Crunchyroll.
