We develop the dynamical core--corona initialization framework as a phenomenological description of the quark gluon plasma (QGP) fluids formation in high-energy nuclear collisions. Using this framework, we investigate the fraction of the fluidized energy to the total energy and strange hadron yield ratios as functions of multiplicity and scrutinize the multiplicity scaling of hadron yield ratios recently reported by ALICE Collaboration. Our results strongly indicate that the QGP fluids are partly formed even at the averaged multiplicity for non-single diffractive p+p events.
