  We propose a new mechanism to communicate between fermion dark matter and the
Standard Model (SM) only through the four-form flux. The four-form couplings
are responsible for the relaxation of the Higgs mass to the correct value and
the initial displacement of the reheating pseudo-scalar field from the minimum.
We show that the simultaneous presence of the pseudo-scalar coupling to fermion
dark matter and the flux-induced Higgs mixing gives rise to unsuppressed
annihilations of dark matter into the SM particles at present, whereas the
direct detection bounds from XENON1T can be avoided. We suggest exploring the
interesting bulk parameter space of the model for which dark matter annihilates
dominantly into a pair of singlet-like scalars with similar mass as for dark
matter.
