I haven't read 'koibito o netorare light novel', but from what the title suggests, the main themes might be centered around love, jealousy, and loss. The idea of having one's loved one 'taken away' implies a sense of loss and the jealousy that would likely follow. It might also touch on themes of self - discovery as the character deals with this difficult situation in their relationship. Maybe the character has to reevaluate their self - worth and what they truly want in a relationship after such an event.
Since I don't have direct knowledge of 'koibito o netorare light novel', based on the words in the title, it may deal with themes related to love and relationship challenges. It could be about the pain and confusion that a character experiences when their lover is involved with someone else. Also, it might explore how the character copes with such a difficult situation, whether it's through trying to win the lover back or finding a way to move on.
I'm not sure as I haven't read this particular light novel. But generally, from the title, it might explore themes of love and betrayal. 'Netorare' often implies a situation where one's partner is being taken away, so it could be about the emotional turmoil that comes with such a situation in the context of a romantic relationship.
I'm not sure specifically about light novels exactly like 'koibito o netorare light novel'. However, some popular light novel series that often deal with relationship themes are 'Sword Art Online' which has complex relationships among the characters within a virtual world setting. Another one could be 'Re:Zero − Starting Life in Another World' where the main character has various relationships with different people in the new world he is in.
Relationships in general are probably a key theme. This includes not just romantic relationships but also friendships and how they interact with the main plot.
Power dynamics. These novels often show how imperial powers exerted control over colonies, like the way they used military force and political manipulation.
Power is often a main theme. Impeachment involves the power dynamics between different branches of government. It shows how power can be challenged and held accountable.
If we assume such a novel exists, it might explore themes like power dynamics. In a sex contract situation, there could be an unequal distribution of power between the parties involved. One might have more control or influence due to the terms of the contract.
Survival is a big one. Characters in the novel often have to figure out how to get food, water, and shelter on the lost island. Another theme could be isolation. Being cut off from the rest of the world can have a huge impact on the characters' mental states.
As I don't have in - depth knowledge of these specific light novels, but generally in light novels, common themes can be friendship, adventure, coming - of - age. So it's possible that 'Karen and Jun' light novels might also touch on these aspects.
Themes of love and relationships are surely present. The grandma's romantic relationships, whether past or present, would be an important part of the story. It could show how she found love in a society that might not have been fully accepting at times. There may also be themes of resilience, as she had to face potential discrimination or misunderstanding, and yet still managed to live her life. And of course, the theme of identity in general, not just sexual identity, but also how being a grandma and a lesbian shapes her overall sense of self.
Identity is a big one. The character who is intersex and a 'golden boy' might struggle with their sense of self, trying to figure out where they fit in society, in terms of gender and also in terms of their special status as a 'golden boy'.
One of the main themes is the exploitation of the vulnerable. In these graphic novels, you often see how traffickers target those who are poor, marginalized or in desperate situations. For example, young girls from impoverished families might be lured with false promises of a better life.
