I watched it after everyone once the group was already chosen.
I preferred Nonaka Shana, she is in Lapillus now. I also loved Su Ruiqi. I like Cherry Bullet so I also supported Bora. Among the members of Kep1er, I like Chaehyun the most.
I didn't watched it but I was quit surprised after seeing a bit of a Japanese survival show that one of the winners is the cousin of a girl who apeard on GP999
