For a smooth bounded domain,, we consider the fast diffusion equation with critical sobolev exponentunder Dirichlet boundary conditionon. Using the parabolic gluing method, we prove existence of an initial datasuch that the corresponding solution has extinction rate of the form $$\|w(\cdot, \tau)\|_{L^\infty(\Omega)} = \gamma_0(T-\tau)^{\frac{n+2}{4}}\left|\ln(T-\tau)\right|^{\frac{n+2}{2(n-2)}}(1+o(1))$$ as, hereis the finite extinction time of. This generalizes and provides rigorous proof of a result of Galaktionov and King \cite{galaktionov2001fast} for the radially symmetric case.
