That's what matters the most.

It's sad that some ENs left and individuals drifted apart, but that's how friendships go sometimes. It's not because they hate each other or want to see the other(s) fail. That's the sad kind of mindset former-friends of Mori held towards her.
I really hope anyone who actually cares about the wellbeing of the people behind the screen don't expect to see bitter rivalries and forced activity. Because that's part of what put Gura into the irrecoverable slump, and it seems some of her fans are preparing to do it to her again.
