Good Riddance (Time of Your Life) – Greenday
Dear Ichigo,
Bet you never thought you'd read this, eh? I wrote it to you because you're the only person in this fucking world that I give a shit about, and I figured you'd be pretty pissed if I didn't give you an explanation. So here we go, explanation. This wasn't your fault, so don't blame yourself, it's for the best. I swear on my life (figure of speech, I guess) that the times we had were fun, actually, they were fucking awesome. You made my life awesome. I'm sorry I had to do this to you but it had to be done. And one last thing, (don't you fucking tell no-one I said this) I love ya, Ichi. See you in the next life,
Grimmjow.
Explanation: 'It's something unpredictable, but in the end it's right. I hope you had the time of your life.' To me that says, Grimmjow went and killed himself. Explanation DONE:)
