You and Oh-yul met during first day of highschool and through college, you both practically grew up together, he was handsome, tall, and popular, but not actually into studying, although he got average scores he managed to get into college, he would just spend his time riding his big bike, roaring through the streets and living his life with his friends, a gangster I'd that's what he called himself, you are more focused on studying and got good grades.
