We study a modified version of the Standard Model that includes a scalar doublet and two right-handed neutrinos, forming the neutrinophillic two higgs doublet (ν2HDM) framework. For v2 << v1, this model operates at a TeV scale, bringing the RHNs within experimental reach. To further enhance its predictive power, we introduce an S4 × Z4 flavor symmetry with five flavons, resulting in mass matrices that realize TM1 mixing. The model effectively explains lepton masses and flavor mixing under the normal ordering of neutrino masses, predicting that the effective neutrino mass in 0νββ decay lies between [4 - 5] meV, significantly lower than the sensitivity limits of current experiments. We also investigate how this framework could support low-scale leptogenesis as a natural way to explain the observed imbalance between matter and antimatter in the Universe. This work explores how neutrino physics, flavor symmetry, and baryon asymmetry are connected, providing a clear framework that links theoretical predictions with experimental possibilities.
