We present simulation results about the interplay between super star clusters (SSCs) and the host dark-matter (DM) halo, with emphasis on the formation of bulges in very late-type galaxies. Simulations show that the NFW halo close to a stable state has no significant response to sinking of circumnuclear SSCs. Generally speaking, while the halo becomes hotter, its central cusp survives. The structures of the formed bulges are similar to what we obtained with fixed NFW halos, but the bulge formation fraction at various stages are smaller.
