  The equation of state (EoS) of neutron star (NS) matter is investigated
considering kaon condensation. Moreover, the tidal parameters related to the
components of binary neutron star mergers are determined and compared to the
constraints of GW170817 imposed on these quantities. In this study, we employ
the lowest-order constrained variational (LOCV) approach and utilize {AV6$'$,
AV8$'$, and AV18 potentials} accompanied by the three nucleon interaction (TNI)
{in order to consider the nucleon-nucleon interaction}. It is known that the
existence of kaons in the core of NSs softens the EoS {and thus} lowers the
value of maximum mass which is expected to be greater than 2 M$_\odot$. Our
results demonstrate that considering kaon condensation with a strangeness
value, a$_{3}$m$_s$=-134 MeV satisfies the maximum mass constraint except for
AV8$'$+TNI potential. However, the calculation of dimensionless tidal
deformability shows that with the decrease of strangeness value, the neutron
star gets less deformed.
