Maho of the Hello! Project group Angerme was out for medical reasons for over a year before they finally removed her from the group photos and list. But we should obviously be hopeful. I took advantage of that inquiry form and sent a "fan mail" message to Ruttan to tell her she is missed.
As for "cognac"? I thought that was really weird too but I'm sure it's just a translation mistake.
I knew this was going to be the case with Ruka... and each day that I waited to find out I prepared myself for the worst, and yet - I'm still so sad and upset. I've somewhat only watched Rojapo from the side since she disappeared because I hated seeing them as a 4-piece, and without Ruka. Now I'm not sure what I'll do. Very sad... but I'm happy for her because she obviously wanted out.
