Phenomenological dynamical models are powerful tools to directly tease out the properties of quark gluon plasma (QGP) from RHIC and LHC experiment data. Recent studies show that high-multiplicity proton-proton collisions produce similar behavior of final hadrons as observed in heavy-ion collisions. The dynamics behind such experimental observation should be investigated through a comprehensive description to reveal whether there exists a universal picture of a reaction from proton-proton to heavy-ion collisions. We establish the dynamical core-corona initialization model as a unified picture that phenomenologically describes dynamical "equilibration" in the initial stage.  We discuss that contributions from QGP fluids (core) and non-equilibrated matter (corona) show non-trivial interplay, which could change the conventional picture of high-energy nuclear collisions.
