We report on the analysis of the microlensing event OGLE-2019-BLG-0825. This event has been labeled as a planetary event by preliminary modeling. From detailed analysis, we find non-negligible residuals from the best-fit static binary-lens model exists. We detect xallarap effect with \(\sim\)5.5 days that can fit the residuals very well and significantly improves \(\chi^2\) values in all data sets. On the other hand, by introducing the xallarap effect, we find that binary-lens parameters like q and s cannot be constrained well, i.e. various binary-lens models are possible. However, we also find the parameters for the source system like the orbital period and xallarap amplitude are consistent between all the possible models. We conclude that the source system consists of a main-sequence star (M-dwarf or K-dwarf) orbited by a low-mass companion (M-dwarf or brown dwarf) with \(P\sim5.5\) days and \(a\sim0.06\) AU. This analysis first demonstrates that xallarap effect with short periods can affect binary-lens parameters in planetary events.
