In quantum theory, black holes evaporate. We adopt this property as the 0th approximation and provide a field-theoretic description of black holes. To do that, we analyze time evolution of a spherical collapsing matter together with the back reaction of (pre)Hawking radiation by solving the semi-classical Einstein eq coupled with N massless scalar quantum fields. We find a 4D self-consistent non-perturbative solution w.r.t. $\hbar$. It describes the most part of the black hole in the semi-classical level while it connects the semi-classical region to the quantum gravity region smoothly. [arxiv:2002.10331]
