It's difficult to determine if TwoSetViolin likes reading fanfiction. On one hand, they are so immersed in the music world that they may not have much time for it. On the other hand, they are creative individuals, and fanfiction can be a very creative form of literature. If they were to give it a try, they might find it fascinating. But until there's some evidence or statement from them, we can only speculate.
I don't really know if TwoSetViolin likes reading fanfiction. They are known for their music content. However, if they do read fanfiction, it could add a new dimension to their interests. Maybe they would enjoy the imaginative aspects of it, but without any statement from them, it's hard to say for sure.
