Description V2028 Cyg shows a B[e] phenomenon. Due to the presence of both cool (K7III) and hot (B4III) components in the spectra, it is supposed to be a binary. Our modelling of the time variability of H alpha line bisectors shows, however, that this hybrid spectrum can originate in one star, which is surrounded by a disc.
