Around July, Cindy left the group to focus on her studies and was replaced by two new members, Kyungsook and Paengi. Shortly after the lineup change, the group made their first comeback as an eight-member group on September 19 with their 1,5st single album "Kiss Me". The same month, Leader’S released their second single "Olympic Korea" on the 28th as a cheering song for the Pyeongchang Winter Olympics, sponsored by the sportswear brand FELICE.

On October 27, TGN Entertainment announced that Leader'S would be reorganized into a 24-member girl group with three sub units: - Leader'S T, consisting of the eight-member lineup of the main group and was already promoting with "Kiss Me" - Leader'S G and Leader'S N, each consisted of eight members, who were going to be revealed later.
