Inspired by the recent measurement of CP asymmetry in the individual mode on LHCb, we study CP asymmetry of the system in the isospin and topological analysis. The ratio between penguin and tree amplitudes in the system is found to be greater than two in most values of the relative strong phase. And is a potential mode to reveal the CP asymmetry of the order of , which would be observed by Belle II in the future. The large CP asymmetry in the system might be understood in the t-channel final-state interaction.
