Early in the third season, a new member, Jeonghan, joined. And after a while, Samuel left for undisclosed reasons. During this season, they participated in missions where the public voted for their favorite member via the official website, and the most voted would compose the "tracklist" for Like Seventeen 2.
Fourth season
This season continued with the same format as previously, i.e., missions and wishes for the formation of *Like Seventeen 3*. No member joined or left during the fourth season.
Fifth season
During the hiatus of Seventeen TV, three members left, Dongjin, Doyoon and Mingming ; there was the entry of a new member, THE8. Unlike other seasons, the fifth season started with a show, in order to display the evolution of the members' skills during the time gap. With only 7 episodes, two of them recorded shows, Seventeen officially closes the TV with a greater interaction with the fans, because for one hour of live they chatted with fans via Ustream's chat.
This season also had votes for the Like Seventeen 4, but was not based on missions, but only in the name of music.
