As many others, I was expecting this to happen sooner or later but I really thought she would stay all of 2014 and then graduate at of the H!P winter concerts.
While feeling sad that she won't be a part of MM anymore I am happy for her

She's really been a great leader and helped the girls get them where they are today.
Hopefully she will get some well deserved rest after her graduation and then she can return to showbiz (if that's what she wants).
