    Recent years, evidence for collective effects has been revealed in pp and pPb collisions when looking at events releasing large number of particles. The experimental observations lead to a debate of the formation of strongly coupled Quark-Gluon Plasma in those small collision systems. Azimuthal anisotropy coefficient (vn) of heavy-flavor particles, and especially the comparison to light flavor particles vn, can shed light on the strength of the coupling between heavy flavor quarks and the hypothesized hydrodynamic medium at a significantly reduces size, and impose further constrains on different interpretations related to the origin of the observed collectivity. In this talk, the most recent results of prompt D0 meson elliptic flow (v2) in high-multiplicity pPb collisions are presented over a wide transverse momentum range. The results are compared to those of strange hadrons, including Kshort, Lambda, Cascade and Omega particles.
