CHIAKI WILL ABSOLUTELY FILL IN THE SILENCE. he would've asked minato "is it okay if i keep talking!" and "blue do you want to watch tv!" and "blue let's go fight monsters!" and if minato ever seemed sad chiaki would just give him a hug...... i feel like if they ever had an exchange about chiaki just being like "YOU SEEM SAD, DOES IT HURT SOMEWHERE" and just tries to put a power ranger or hello kitty bandaid wherever minato says it hurts.

THE LETTER WOULD'VE STILL WORRIED HIM IT'S FINE. he probably would've been like "IT'S OKAY, HE'S MY BLUE, I'LL FIND HIM SOMEDAY, I SWEAR IT" THE BONDS OF HEROES ARE UNBREAKABLE

that's all the support that chiaki needs omg what a good blue
