  We make use of the ASAGAO, deep 1.2 mm continuum observations of a 26
arcmin$^2$ region in the GOODS-South field obtained with ALMA, to probe
dust-enshrouded star formation in $K$-band selected (i.e., stellar mass
selected) galaxies, which are drawn from the ZFOURGE catalog. Based on the
ASAGAO combined map, which was created by combining ASAGAO and ALMA archival
data in the GOODS-South field, we find that 24 ZFOURGE sources have 1.2 mm
counterparts with a signal-to-noise ratio $>$ 4.5 (1$\sigma\simeq$ 30 - 70
$\mu$Jy beam$^{-1}$ at 1.2 mm). Their median redshift is estimated to be
$z_\mathrm{median}=$ 2.38 $\pm$ 0.14. They generally follow the tight
relationship of the stellar mass versus star formation rate (i.e., the main
sequence of star-forming galaxies). ALMA-detected ZFOURGE sources exhibit
systematically larger infrared (IR) excess (IRX $\equiv
L_\mathrm{IR}/L_\mathrm{UV}$) compared to ZFOURGE galaxies without ALMA
detections even though they have similar redshifts, stellar masses, and star
formation rates. This implies the consensus stellar-mass versus IRX relation,
which is known to be tight among rest-frame-UV-selected galaxies, can not fully
predict the ALMA detectability of stellar-mass-selected galaxies. We find that
ALMA-detected ZFOURGE sources are the main contributors to the cosmic IR star
formation rate density at $z$ = 2 - 3.
