My7

My7 is a reality show that features 16 trainees from South Korea-based Angelfish Entertainment. It featured the formation process of the agency's first group; Crush. The 11 trainees are put through various activies and missions - such as singing, rapping, modelling, and acting - to determine the girls who will debut as part as the 7-membered idol group.

Format
Each episode, the trainees are assigned a mini-challenge and a maxi-challenge. The mini-challenge can be anywhere between modelling in the streets of Seoul to taking part of a mock commercial. The winner, or winners, of the mini-challenge play a key point in the maxi-challenge, such as determining teams or concepts.

After each maxi-challenge, the girls are told whether they are safe or in danger of being eliminated. The girls who are safe are told which of them performed the best of the week. The remaining safe girls continue on to next week without recognition. The girls who are in danger are then scored by the judges on a scale of 1 to 10. The girl with the least number of points is eliminated.

In episodes two through four, a contestant would be eliminated, afterwards one or more trainees would be announced as an official member of the group. During the finale, one girl was eliminated, automatically advancing the remaining three as members. Once a trainee was eliminated, she would no longer participate in the show. However, if a trainee was announced as a member, she would not participate in the mini-challenges, but she would participate in the maxi-challenges with other announced members. For the finale, all the announced members will perform together.
