Unit groups' flop was one of the most heartbreaking moments in Kpop, cuz it literally went against the premise of the show. I think they did a lot of the things wrong, including mix gender format of the show.
The problem with Peak Time on the other hand is that the decided to air this at the same time with Boys Planet. Looks like a tough road ahead for it, but I really hope it does well, so we get the female version of it
