The second stage was 'competition'. The unfinished 49 people formed a total of seven unit teams, where they would vividly confirm their intense competition. The third stage was 'growth', a process of the birth of a 24-member Boys24, which would be confirmed in the theater. The final stage was 'evolution'.
