We study an exciting dark matter scenario in a radiative neutrino model toexplain the X-ray line signal at $3.55$ keV recently reported by XMN-NewtonX-ray observatory using data of various galaxy clusters and Andromeda galaxy.We show that the required large cross section for the up-scattering process toexplain the X-ray line can be obtained via the resonance of the pseudo-scalar.Moreover this model can be compatible with the thermal production of darkmatter and the constraint from the direct detection experiment.
