Well, the theme of secrecy is quite common. Wolfstar has to hide their relationship due to various reasons, and jegulus often has elements of secrecy too, maybe because of family differences or the wizarding world's politics. Also, the theme of growing up and maturing. We see how these characters develop from their Hogwarts days into more complex individuals dealing with the real - world problems of the wizarding world.
One great source is Archive of Our Own (AO3). There are numerous well - written wolfstar and jegulus fanfictions there. For example, 'The Marauders' Reckoning' is a popular one. It delves deep into the relationships between the characters, with a well - crafted plot that keeps you hooked. The characterizations are on point, staying true to the essence of the original characters while adding new and interesting dimensions to them.
Sirius could be outraged. He might feel that it's inappropriate to create fictional relationships between his best friend and his brother. He could even try to find out who is writing it and ask them to stop. However, he also might realize that he can't really control what others write in their free time.
Support from each other is also a major theme. Wolfstar's relationship is often depicted as a source of strength. They rely on their deep connection and love to help the one with the disorder through tough times. It could be things like Sirius encouraging Remus to eat proper meals.
Another theme is the struggle with their own identities. Sirius, being from the Black family with all its dark secrets and Remus being a werewolf, both have issues with how they see themselves. In many fanfictions, this self - discovery is intertwined with their growing feelings for each other. They learn to accept themselves through accepting each other.
The theme of secrecy also pops up a lot. Given Sirius's situation as a fugitive and Remus's secret as a werewolf, fanfictions play with how they have to keep their relationship and themselves hidden from the rest of the wizarding world, which adds an element of mystery and tension to the stories.
They might be quite shocked at first. Since Wolfstar is a ship about Sirius and Remus, it's a modern interpretation of their relationship. The Marauders might not understand some of the modern concepts and language used in the fanfiction.
I also like 'Jegulus: A Love Story'. It's a simple yet effective fanfic that focuses on the pure love between James and Regulus. It doesn't have too many over - the - top plot twists, but rather just tells their story in a very heartfelt way, which makes it really stand out.
One common theme is the struggle against prejudice. Since James is from Gryffindor and Regulus is from Slytherin, there's often a theme of breaking through the house - based biases that exist in the wizarding world. Another theme is secrecy. Their relationship is often depicted as something that has to be hidden from others.
Sirius might like it because he's always up for something new and different. He could find the fanfiction's ideas about his bond with Remus fascinating. Remus, though, would be uncomfortable. He values his privacy and the fanfiction might make him feel exposed. James would be curious. He'd want to explore what others think of their group, so he might be interested in the fanfiction in a general sense. Peter would be indifferent. He doesn't really care much about this kind of thing.
