I guess that's karma for you. I/Cuckoo was gaining people's trust and betraying them. The one person who she could confide in and even trusted enough to reveal her secret to turned out to her supervisor. From what I can tell, there's no true happy ending. The only other ending is if you listen to music too much and you get arrested too. Either way, you realize you're just a pawn. A tool for the anti-music government. You get the vacation you wanted and you won't even be able to enjoy it. You got joy out of creating and sharing music. You felt comfort in finding someone to talk to. But they were both lies. And now it's all over. And you can't go back to blind loyalty anymore.
