Considering various theoretical and phenomenological constraints, we have found the best-fitted parameter set in the type-I two Higgs doublet model. This optimal parameter set can be tested by precisely analyzing specific decay processes of D^+, B^0, and the light Higgs boson. For a direct search of the model at future colliders, we have proposed an investigation of the t tbar b bbar signal at the ILC to detect the new physics of the model.
