A theoretical review of the $D^{+}_S\rightarrow K^+K^-K^+$ decay is shown by introducing the $W$-external emission topology and its visualization using Dalitz plots. The model relies on chiral perturbation theory ($\chi PT$) with resonances, the heavy quark spin symmetry (HQSS), form factors, and two bodies' final states interactions. The resulting amplitude for the $D^{+}_S\rightarrow 3K$ decay coincides with the decay channel phenomenological knowledge, by the presence of the tail of $f_0(980)$ at the beginning of the phase space and the dominance of the $\phi(1020)$ resonant structures. Additionally, the model implemented has the freedom to be adjusted with future fittings.
