  We propose a model to describe the late-time cosmic acceleration in the
context of the constant-roll model. By considering a coupling between massive
neutrinos and the quintessence, the onset of evolution of the quintessence is
related to the neutrinos' behavior. When the neutrinos become non-relativistic,
the dark energy density increases from zero and results in late-time cosmic
acceleration alleviating the coincidence problem. The quintessence potential is
such that it evolves under the constant-roll condition giving rise to
persistent late-time acceleration.
