They are competing shows. both are survival shows to form a girl group from 100+ trainees at the beginning. The shows follow the same formula. There's the 1st stage, 1st elimination, 2nd stage, 2nd elimination, 3rd stage, collab stage, 3rd elimination, and final performance and final elimination. each of the eliminations will eliminate around half of the trainees and are decided by public votes. What makes the shows even more similar is the shows overlap in their broadcast dates.
