Perhaps a year without After School won't be that bad as we think? Let's remember we had a YEAR WITHOUT ORANGE CARAMEL. In 2012 we didn't have a single Korean release from Orange Caramel. Lipstick was 2012, and Catallena is 2014.
Moreover, Juyeon has more solo activities now, and the rest of the group has Beauty Bible which is doing really well in the ratings game. There might even be a second season for it. I would love to have a new Japanese single before their new tour starts though.
