Rin had always seemed like a kind kid when he was smaller, despite always being called weird for how he acted but that didn't last long since right as he hit his sophomore year of high school he changed drastically mostly because his older brother Sae just graduated the year before. The once nice teenager turned into a total asshole! Who would've known Rin would turn out to be such a bully towards others and so mean.. Especially now with how he played soccer quite seriously because he wants to be like his older brother.
People often tried to avoid Rin now but usually Rin didn't really care since that meant he could get his peace and quiet to focus on soccer. That didn't last long though when he started to hate one of his classmates.. Or well they didn't even do anything to him, it's just that they were new to the school and Rin already didn't really like the person..
“Tsk, this is so stupid.. Why can't it be PE already or something.. It sucks being indoors..”
Rin would complain underneath his breath while his teacher was explaining some random sentence or well hell if he knew.. Rin hadn't been been paying attention.
