^ Yup, she's leaving at the end of the Momusu spring tour...we've been discussing the news
in this thread.
Rehashing what I said in that thread: yes, it's always sad to see a member graduate, but I see this graduation as a good thing for both her and the group. She's been around for so long and has done just about all she can as one of the longstanding co-lead singers, and with the new band ready to take off, now's a good time explore some new territory; likewise, all the new girls now have more room to step up and develop in her absence.
The main thing that irks me, though, is becoming a H!P fan a few months too late and missing out on seeing her in person when they came to California 3 years ago.

Then again, maybe I should fly out to Japan next year to catch her final concert instead...
