AU Saionji from my Jarjammed ending AU wherein Saionji returns to Gentaro's world but is still stuck in his own time, fifteen years before Gentaro will remember him. He ends up struggling with trying not to interfere with Gentaro's timeline. (i.e. should I try to save his parents or not?) (He writes a letter that he never sends warning them about car wrecks, because no matter how he tries, "Please stay safe when driving in motor vehicles. And take good care of your son." sounds like a threat.)
He does send a letter after Gentaro's parents die, saying "Your parents loved you very much. And they knew you were going to grow up to do great things." and signing it as, "a friend."
Later on he starts in as a special instructor at Amanogawa, at the Kendo Club, and Gentaro is all like "WHAT UP TEACH WE'RE GONNA BE BUDDIES" and Saionji is just like "We already are." And Gentaro's all !?!?!?!??!?! but he can totally tell they actually are buddies, and he's kind of confused as to how he forgot it somehow.
But later when he catches up there's a tearful reunion that I might draw later??? I don't know I'm in love with this terrible AU. Anyway this is Saionji as he'd look in 2012, at age something like 33.
