X-Fire (2015)

A competition/survival show to produce a boy group. It starts out with 16 contestants and two teams. The mentors each choose their members based off of their debut performances, and then form pairs within the team. Therefore each team has four pairs of two, and eventually each pair is put up against the other team. There is also three judges who score the performances, and they are quite strict but are very professional, providing rationale to their opinions. At the end of each episode, the teams get ranked, and after some rounds, members get eliminated and the rest gets reorganized to better suit the change. The pairs soon turn into groups of three and so on. The show continues with many powerful performances, revealing significant improvement of the contestants.
