  Motivated by the Belle Collaboration's new observation of $Y(4626)$, we
investigate the possibility of its configuration as a $P$-wave
$[cs][\bar{c}\bar{s}]$ tetraquark state from QCD sum rules. Eventually, the
extracted mass $4.60^{+0.13}_{-0.19}~\mbox{GeV}$ for the $P$-wave
$cs$-scalar-diquark $\bar{c}\bar{s}$-scalar-antidiquark state agrees well with
the experimental data of $Y(4626)$, which could support its interpretation as a
$P$-wave scalar-scalar $[cs][\bar{c}\bar{s}]$ tetraquark state.
