Query: Why is TeV-scale a geometric mean of neutrino mass and GUT-scale?   Among three typical energy scales, a neutrino mass scale ($m_\nu\sim$ 0.1
eV), a GUT scale ($M_{GUT}\sim 10^{16}$ GeV), and a TeV-scale ($M_{NP}\sim 1$
TeV), there is a fascinating relation of $M_{NP}\simeq \sqrt{m_\nu\cdot
M_{GUT}}$. The TeV-scale, $M_{NP}$, is a new physics scale beyond the standard
model which is regarded as supersymmetry in this letter. We suggest a simple
supersymmetric neutrinophilic Higgs doublet model, which realizes the above
relation dynamically as well as the suitable $m_\nu$ through a tiny vacuum
expectation value of neutrinophilic Higgs without additional scales other than
$M_{NP}$ and $M_{GUT}$. A gauge coupling unification, which is an excellent
feature in the supersymmetric standard model, is preserved automatically in
this setup.
