Well, it all starts out with Kirito wanting to try out solo stuff anyway. And then he meets up with Kiyoharu(or whatever the name is), who is this tough guy that he's got something going with.
Anyway, it's supposed to just be a fling, but he so severely ****s up Aijis head that Aiji one day, out drinking all by himself ends up with random guy(who is sort of in the same situation), wakes up the next day and realizes what he's done.
He needs to talk to someone and chooses Jun. He agrees with Jun not to tell Kirito about it.
Anyway, coming back from seeing Kirito, Jun tells Aiji that he thinks Kirito knows.
Turns out Jun didn't tell him, but he told Takeo, who is Kohtas buddy-buddy, and Kohta grabs the first chance he get to throw in his brothers face that "Haha, you ****** up!"
Aiji decides he has to see Kiro, so he goes to the place where he's at(photostudio, I think, but I'm not sure). Soon as Kiro sees him all he does is look up at him before he sais: "Get out, I don't want to see you".
So basicly, they're in trouble, but they will get out of it. Who knows? Maybe Kiro will finally swallow his pride.
(Before you ask, this is not something I read in a fanfic!)
