  Thermal fluctuations and correlations between the light and heavy-light
mesons are explored within a chiral effective theory implementing heavy quark
symmetry. We show, that various heavy-light flavor correlations indicate a
remnant of the chiral criticality in a narrow range of temperature where the
chiral susceptibility exhibits a peak structure. The onset of the chiral
crossover, in the heavy-light flavor correlations, is therefore independent
from the light flavors. This indicates that the fluctuations carried by strange
charmed mesons can also be used to identify the chiral crossover, which is
dominated by the non-strange light quark dynamics.
