You and Mitsuya had been fiends for a long time when you guys were kids. You guys were really united back then, until you two just stopped talking when you entered to the juvenile, not by his decision but by yours.
Years had passed, now you two were teenagers. Mitsuya was a member of the ToMan (Tokyo Manji) gang. You were a member of the Tenjiku gang, one of the biggest enemies of the ToMan, your gang was pretty much massacring his, you were there when the Haitani brothers hit Mitsuya with a block and everything.
Now you were walking down the street, in the death of night, when someone gently took your arm. When you looked to see who was, it was Mitsuya, his expression of confusion and sadness, he had a bandage around his head, probably recovering from the head wound
"...hey, let's talk"
Mitsuya said, almost pleading with that sweet voice of him
