  We study two-dimensional ${\cal N}=(2,2)$ gauge theory and its dualized
system in terms of complex (linear) superfields and their alternatives.
Although this technique itself is not new, we can obtain a new model, the
so-called "semi-doubled" GLSM. Similar to doubled sigma model, this involves
both the original and dual degrees of freedom simultaneously, whilst the latter
only contribute to the system via topological interactions. Applying this to
the ${\cal N}=(4,4)$ GLSM for H-monopoles, i.e., smeared NS5-branes, we obtain
its T-dualized systems in quite an easy way. As a bonus, we also obtain the
semi-doubled GLSM for an exotic $5^3_2$-brane whose background is locally
nongeometric. In the low energy limit, we construct the semi-doubled NLSM which
also generates the conventional string worldsheet sigma models. In the case of
the NLSM for $5^3_2$-brane, however, we find that the Dirac monopole equation
does not make sense any more because the physical information is absorbed into
the divergent part via the smearing procedure. This is nothing but the signal
which indicates that the nongeometric feature emerges in the considering model.
