Hey Shinji, Rei too, I don't know if this would ever reach the specific two I knew in canon, but, all of you are welcome to read this, if it helps you.
I'm sorry, I was an awful friend to you two, I let my jealousy control me way too often and just, I don't know. I was never there for you two.
Rei, I won't ever be able to understand you, but I did care, even if it was too late for me to voice it by the time you were gone. I wish I could've done something, anything to prevent your demise, even if you choose to do it for Shinji. You're braver then I'll ever be, kinder too. I don't know if you considered me as a friend, but, I appreciate you nonetheless, and I miss you. I hope you're doing well wherever you are now!
Shinji, I could say a lot about you, lecture you, but you've heard enough I assume. We both were troubled, everything that I started, despite knowing it wouldn't fix anything, I'm sorry, I really just hurt you more then even helping you. You tried to reach out to me despite the fact I treated you terribly, I admired that, a lot. I really hope you're doing better now, and if I could, I'd like to hear you play the Cello one more time.
I know I've already said this, but I hope you two are doing well, things have been going well for me, but I still think about you two a lot.
