GW190425 is the second gravitational wave (GW) event caused by a binary neutron star (BNS) merger. We report the result of the follow-up observation of GW190425 by the Gravitational-wave Electromagnetic-wave (EM) Counterpart Korean Observatory (GECKO). Our observation demonstrates that GECKO can detect EM counterpart of a GW170817-like event.
