What i don't understand about the Chuu situation is that BBC is keeping on posting her pica and she is carrying her activities with the group like nothing is going on usually when these type of things happen the idol will halt their activity with the group and the company will slowly strat acting as of the member was never part of the group to begin with
they aren't giving her managers and she has to drive alone for her individual schedules as far as i heard plus she won't be part of the world tour so it's not like everything is normal.. maybe there is a few more days before her contract is officially over and until then BBC is still promoting with her to make this comeback as successful as they can before she the most famous member actually leaves
