  We find that the emission line object OGLEJ005039.05-725751.4, a member of
the cluster OGLE-CL SMC 64, exhibits a peculiar light curve pattern repeating
with a recurrence time of 141.45 days. The light curve resembles periodic
outbursts with a duty cycle of 20%. A second long-cycle of 2500 days is also
detected in the photometric dataset. Two X-SHOOTER spectra obtained at minimum
and maximum reveal a Be star dominating at minimum light resembling the
Classical Be star 48 Lib. The larger H$\alpha$ emission, the stronger NaD
absorption and the appearance of emission in the infrared Ca II triplet at
maximum, might indicate periodic mass transfer in a complex binary system.
