We explore the possibility that all electroweak symmetry breaking (EWSB) comes from the strong dynamics of Technicolor while these are the only quarks which receive masses through Technicolor dynamics. We assume the leptons are not embedded in a representation of Extended Technigroup. In this paper we suggest a model where the leptons receive their masses through the loop corrections which includes at least one closed quark loop. For this purpose we introduce model based on private family SU(2) scalar two doublets which interact very weakly with the Standard Model(SM) fermions and which do not condense at tree level. Assuming quark/lepton universality of suggested Yukawa interactions the model becomes strongly predictive and we calculate mass contributions to the all known SM lepton gauge eigenstates. Up to not yet explored mixing, the model suggests that the lepton mass hierarchy comes from the quark mass hierarchy. Within a single universal Yukawa coupling the absolute values of masses for neutrino family eigenstates are calculated from 3loops diagram. LHC observed 126 GeV scalar is interpreted as a Technisigma which is made from quarkophilic Techniquarks, which interaction with leptons is induced by quantum loops as well.
