  In this paper, we study the topological properties of the Gromov boundary of
the fine curve graph of an orientable finite-type surface of genus at least 2.
This graph consisting of topological curves has much richer dynamics than the
classical curve graph. Using the techniques introduced by Wright [Wri23], we
show that this boundary is (path) connected and that the spheres in
non-separating fine curve graph are connected.
