Through both perturbative and non-perturbative methods, we show that the quantum effect can play a crucial role in shaping the nearhorizon geometry, and that the existence of the horizon requires fine-tuning. © 2018, The Author(s).Black Holes; Classical Theories of Gravity[SDGs]SDG7journal article10.1007/JHEP11(2018)0562-s2.0-85056342278WOS:000449816600002https://www.scopus.com/inward/record.uri?eid=2-s2.0-85056342278&doi=10.1007%2fJHEP11%282018%29056&partnerID=40&md5=20ef32c34b6e4c201b77b9f4e8ca0212
