We present here a study of the direct and indirect detection prospects of a generic dark matter simplified model, in which the Majorana dark matter interacts only with a Standard Model lepton and a pair of uncolored mixing scalar mediators. We first show that the mixing angle significantly changes the feature of internal bremsstrahlung, as well as the flux ratio of γγ and γZ line signals. The CP-violation phase will introduce an polarization asymmetry in the γγ final state. Then we study the direct detection prospect and discuss the complimentarity of these two search strategies.
