Performed are fully self-consistent N-body simulations of the star cluster near the Galactic center using a new algorithm, which combines the tree and direct schemes, and compared the results with that obtained with the ''traditional'' N-body simulations where the dynamical friction is calculated analytically using the dynamical friction formula. It is found that the orbital evolution of the star cluster in full N-body simulation is much faster than those in the ''traditional'' simulations. The timescale problem of the star cluster inspiral scenario is not so severe as suggested by previous ''traditional'' N-body simulations.
