seeing those wedding dress pictures!!!
jst like that old song Ah~, ii na! Thsoe screencaps look great, but here is the full picture, featuring someone else playing the groom(wouldn't know who though, the face seems unfamiliar, it wasn't featured on the last H!M episods so can't be H!P related...)
I also think that it would have been announced by now if she was gonna leave H!P, I mean she's not really fit to have a grad concert but I think since it's not all scandal-y if she were to she would be allowed one, probably.
If I were her, I'd try to keep all my options open.
