It's hard to say exactly without more context. Maybe he has a strong dislike for fanfic related to their world or characters. It could be that he feels fanfic distorts the 'true' story or characters in some way that he doesn't like.
He might be frustrated with the way fanfic writers are using their characters. Maybe they're making the characters do things that are out of character.
Overcoming personal challenges is also a frequent theme. Both Barry and Oliver have their own personal demons. In fanfics, they can support each other through these challenges. For instance, Barry might help Oliver deal with his past traumas, while Oliver could give Barry advice on how to handle the pressure of being a superhero in the public eye.
It's hard to say for sure if there is a great 'barry sings for oliver fanfic' without actually searching. But fanfic writers often come up with creative and unique ideas. Maybe there's one where Barry sings for Oliver in a really touching or humorous way. You should try searching on platforms where fans share their works to find out.
There could be such a fanfic, but it's not something that's commonly known or easily found. Fanfic communities have different levels of popularity and content. Some focus on more mainstream or positive storylines, while others might explore more edgy or controversial topics. However, if this fanfic involves explicit or inappropriate content, it may not be present on most legitimate fanfic platforms. Additionally, the names 'Barry' and 'Oliver' could be from various fictional universes, so without more context, it's difficult to determine the existence of this specific fanfic.
I haven't come across a 'Barry loses virginity to Oliver' Olivarry fanfic myself. Fanfics cover a wide range of themes and scenarios, but this one might be a bit more niche. It's possible that it exists in some corner of the fanfic world, but it could also be that no one has written it yet. Maybe if you reach out to Olivarry fanfic communities or forums, you might get more information.
Some dedicated superhero - themed forums might also have 'barry oliver fanfic'. These forums are often frequented by fans who are passionate about the characters and might share their own fan - created stories. However, the quantity might be more limited compared to the big fanfic platforms like fanfiction.net and AO3.
One common theme is the internal conflict within Barry. He often struggles with whether to reveal his feelings or keep them hidden for the sake of their friendship or their superhero duties.
I'm not sure if it's still up, but 'Barry's Heart for Oliver' was a really interesting fanfic. It explored the idea of Barry having a crush on Oliver in a more complex way, dealing with issues like their different personalities and how that might affect their relationship if Barry ever confessed his feelings.
One great 'barry and oliver fanfic' is 'The Flash and the Arrow: Allies Forever'. It shows their friendship and how they team up to face a new super - villain in Central City and Starling City. It has great character development and exciting action scenes.
