安重根
On April 12, AOA aired their reality show "Channel AOA" on OnStyle Live. The group came under widespread scrutiny following their appearance on the reality show when members Jimin and Seolhyun failed to recognize An Jung-geun in a game challenge they had performed on the series. Following the outrage and criticism, the members issued a public apology for their actions. In May 2016, they released their fourth mini-album entitled "Good Luck" with the lead single of the same name. The song peaked at number 2 on the Gaon Digital Chart and the album sold over 40,000 units.
