Why can't one say no to manga?

Well, it could be that such a statement might go against the theme or the intended message of the Benten manga. Or perhaps it might offend the fans or creators. There could be multiple reasons.

It could be due to various reasons. Maybe the opponent is too strong or there are unforeseen circumstances.

There could be a bunch of reasons. Maybe their social statuses don't match, or there's a family feud going on. Or perhaps there's a prophecy preventing the marriage.

The main reason could be that Crunchyroll has partnerships and agreements that don't include offering manga. Or perhaps they haven't made the necessary arrangements with manga publishers to make it available on their platform.

It might be that the story has a plot twist where their love is forbidden for mysterious reasons. Or perhaps the duke is already committed to someone else or has a hidden agenda that makes marriage impossible.

Maybe it's because of the lack of proper study materials or guidance. Without clear resources and instructions, it can be tough to make progress.

It could be that doing it would violate the established rules or plotlines of the manga world. Sometimes, certain actions just don't fit the context or the character developments.

Maybe it's because the plot doesn't require it or the rules of that manga world prevent easy leveling up.

There could be several reasons. First, manga has a wide range of genres to suit different interests. Also, the way it presents emotions and adventures can be very immersive. Sometimes, it becomes a form of escape from reality.

It could be due to various factors. Maybe the challenges are too overwhelming or the character lacks the necessary skills and confidence.
