A complexity-free solution is being presented here within the framework of the Einstein-Hilbert (EH) action. The complexity-free method, i.e., 
, yields a linking equation between 
and 
, reducing the complicated problem of two metric potentials to a single metric potential problem. This provides a simpler approach for solving the field equations, capable of producing physically insightful solutions. To support its physical validity, we have analyzed parameters such as pressure, density, anisotropy, causality, etc., in conjunction with stability considerations based on the adiabatic index and the static stability criterion. Additionally, it gains further support through the incorporation of constraints on the mass and radii of neutron stars derived from the GW 170817 event, thereby predicting the radii of both massive and less massive neutron stars and generating an 
curve.
