Supersymmetry is undoubtedly a popular candidate for physics beyond the Standard Model. However, the origin of soft supersymmetry breaking masses has been usually depicted in the literature through extra hidden/mediating sectors. Thus, a simple theory for the generation of the soft masses would be more compelling. In this talk, I will present a prototype model with the four-superfield interaction term being constructed from a single chiral superfield. The dynamically developed vacuum superfield-squared condensate then gives rise to supersymmetry breaking and soft masses. No other messenger sector, or hidden sector is needed. Moreover, the analysis of effective theory picture and the generation of Goldstino will be also discussed.
