  Recently, it has been argued that a spherical-like spectrum emerges in the
SU3-IBM, opening up new approaches to understand the {\gamma}-softness in
realistic nuclei. In a previous paper, {\gamma}-softness with degeneracy of the
ground and quasi-{\gamma} bands was observed. In this paper, another special
point connected with the middle degenerate point is discussed, which is found
to be related with the properties of 196Pt. This emergent {\gamma}-softness has
also been shown to be important for understanding the prolate-oblate asymmetric
shape phase transition. The low-lying spectra, B(E2) values and quadrupole
moments in 196Pt are discussed showing that the new model can account for
several observed features. This is the first part of the discussions on the
{\gamma}-soft-like spectrum of 196Pt.
