I'm not sure specifically as 'unseemly' is a rather broad term. It could potentially be about a lady who behaves in a way that is considered improper according to the social norms of the story's setting. Maybe she challenges the traditional roles or values in the society depicted in the novel.
People who like stories about complex female characters might be interested. Those who enjoy exploring the boundaries of social norms through literature could also be drawn to it.
Well, the spoilers for a manga like this could involve plot twists like finding a unique diet method that works wonders or facing setbacks that make the journey more complicated. Maybe there's a surprise friendship that helps with the diet too.
For truth, we can ask family members 'What's the most embarrassing but funny thing that happened to you at a family gathering?' For dare, 'Draw a family portrait in 5 minutes.' These are simple and clean ways to play truth or dare in a family, without any inappropriate elements.
Perhaps the perception of her 'unseemly' behavior is due to misunderstandings. It could be that she is trying to fit in a new social circle and is overdoing it. For instance, if she is new to a group that has a more liberal style, she might be adjusting in the wrong way. The key is to communicate clearly with her about what is acceptable and what isn't.
Well, spoilers in light novels related to gamers can be really annoying. For example, if you're into a game - based light novel series and someone reveals a major plot twist about a character's in - game power - up or a crucial event in the game world that the characters are part of. It can ruin the excitement of discovery when you finally get to that part of the novel.
Well, there are some major plot turns in 'A Will Eternal' that you wouldn't expect. However, I suggest you discover them yourself while reading to fully enjoy the story.
