it's not the one i was talking about unfortunately :( the older guy was alr done w school and i dont remember much ab the what the younger one used to do
another detail i can add is how people would literally kill to ride on the older guy's bike as a plus one lol but he wouldn't ever allow anyone no matter how much they begged him the younger one did get that privilege and a leather jacket w the gang's emblem at the very end tho ^^ thank you for trying
YES THANK YOU JESUS
i don't remember a lot of the plot bc i read it a long time ago but basically the story centers around a younger mc and another who's older by a couple of years and the older one used to be part of a gang when he was younger. think fast bikes and leather jackets with their very own emblems in the back. but now he's left that lifestyle to work as a hairdresser.
he still hangs around with his gang to go on evening rides and i can vaguely recall the younger guy really admiring the older one. i think he was well respected by everyone in that gang actually. the older guy had shoulder length black-ish hair and younger had colorful (i dont remember which color lmao) hair.
