"Dear" past Corso,
things went better than expected: Reborn is an awesome place and we somehow managed to make a lot of friends! But there's a little problem (bigger than "little"): me, and that means you. You think you know how broken we are, but the situation is worse. Soon you'll understand what being Unown means and why I chose this avatar. The worst part is that even here you'll make enemies because I/you/we are stupid. I don't think there's anything we can do to fix us at this point, try writing to kid Corso and tell him to buy popular games, play football and make as many friends as possible. That's what I'm doing with our nephew.
About university... Physics is nice, there are cool people there too. Unfortunately, you won't be "the one we want to be" there (I know, there's always someone spoiling our plan, but we know we're getting weaker) but exams should go pretty well. Oh before I forget: third year, be careful of something called "Struttura della Materia". They'll tell you it's the hardest subject in the entire course, and they're right. DO NOT UNDERESTIMATE IT! STUDY THOSE THINGS EVERY DAY! BUY THE BOOKS! Start drinking coffee if necessary! I know, I sound crazy, but PLEASE trust me!
Uh some other news... you're still short, but keep trying (or not, it won't affect me anyway). She still doesn't like you, but you'll see both of them from time to time. Good thing, you won't suffer as much as you did before.
Some useful tips: DON'T BE TOO CLINGY WITH THEM! I know it would seem the most natural thing to do but PLEASE DON'T!
And if you feel something might have bad consequences, FOLLOW YOUR INSTINCT AND DON'T DO IT! (this doesn't apply to something called "Drama Club")
Speaking of clubs... mafia games are important, "just like football" I'm sure you understand...
Eh, but if you're like me (and you ARE me), I can already tell this letter won't prevent you from making the same or similar mistakes. If that happens... you'll deserve what comes next...
Please be careful
Corso
