A common theme could be friendship. Given their relationship within their group, fanfics might explore the deep bond of friendship between chuu and yves. Another theme could be adventure, where they embark on some exciting journey together.
Adventure is also a theme. Writers might create scenarios where they embark on an exciting journey, perhaps in a mysterious land, which tests their relationship and individual strengths.
Well, given that it's called 'The Whale', the whale is surely a central character. If the story delves into the whale's environment, there could be a whole host of other characters. There might be schools of fish that the whale preys on or befriends, other whales with which it mates or migrates. And if there is a human element, it could be a sailor who spots the whale from afar and is in awe of its size and beauty, or a scientist who is trying to study the whale's behavior. However, all of this is just conjecture until one actually reads the story.
I'm sorry, I don't have a specific chuu and yves fanfic to recommend directly. But you can try looking on some fanfiction websites like Archive of Our Own (AO3). There are often many fan-written stories about different pairings in the K - pop world, and you might be able to find some great chuu and yves fanfics there.
Some chuu yves fanfics explore the idea of them being in a parallel universe where they are not idols but regular students. It shows a different side of their personalities as they navigate through normal teenage life, with school, friends, and first loves.
The appeal lies in its combination of fantasy elements and emotional depth. The plot keeps you engaged, and the visuals are stunning. Also, it offers a refreshing take on common themes.
I'm sorry, I haven't actually read 'The Whale' by Yves Theriault directly. But generally, it might be about the life of a whale, perhaps its journey in the ocean, its interactions with other sea creatures, and its struggle for survival in the marine ecosystem.
Some loona fanfics focus on the relationships between the members. There are stories that show their deep friendships and how they support each other through tough times, like during a fictional concert tour where they face various challenges but come out stronger together.
