The broader album concept has been framed around the members’ inner growth. Pickcon reported that “PUREFLOW” pt.1 deals with the change of the five members, who could become stronger because they knew fear, and described the project as extending the group’s earlier narrative from “FEARLESS” and “ANTIFRAGILE” toward accepting fear. 5
