This is probably how it was when a lot of 1st/2nd gen momusu left and 4th gen joined
It's crazy fukuda asuka was only in the group a year and 7 months. and aya ishiguro was only a member for like 2 years. And now like 13 years later the majority of people are like Who?
But yuuka and saki leaving is so devestating? imo it doesn't change how much i like smileage that they left ><
