According to OSEN on November 2, a strict dating ban has been notified to the contestants of the show. In fact, it's reported that male and female trainees are separated and mostly kept away from talking to one another on the sets.

A rep from one contestant's entertainment agency stated, "We have strongly enforced the dating ban to the trainees. It's part of the producers' request and it also means they're not focusing hard if they allow feelings to develop. We have warned them, saying they could be expelled from the program."

Another insider commented, "Some viewers are concerned and/or curious about that part (dating). They're kids who are extremely talented and at the age where they're curious about the opposite sex but it seems like they're being cautious themselves."

Last week, 'Mix Nine' finally unveiled its cover. The second episode will be airing this Sunday, November 5.
