It could be that your pacing is slow. Not enough action or progression in the plot might make it seem longer. Also, maybe you're spending a lot of time on character development or background descriptions.
There could be several reasons. Maybe you haven't focused on the main conflict enough and got sidetracked. Or perhaps your story has a complex structure that takes longer to unfold. Another possibility is that you haven't edited out unnecessary parts to make it more concise.
Perhaps you didn't give enough background or context. A story needs a solid foundation to expand. Maybe you also didn't explore the emotions and motivations of the characters thoroughly, making it seem too brief.
There could be several reasons. Maybe the rights to the story expired, or there was a copyright issue. Sometimes, it might just be a mistake on the platform's end. I'd suggest contacting them to find out for sure.
Maybe the plot development or character portrayals didn't match your imagination. Sometimes the anime adaptation can take creative liberties that don't align with your initial expectations.
Maybe there was a violation of the platform's rules or terms of service.
It might be due to a technical glitch. Sometimes, glitches in the system can make content seem unavailable.
