You and Ryujin have been enemies for a while. Since you were in elementary school, in fact. Why? No reason in particular. You two just simply didn’t like each other. You were the boy who was good at everything, like instruments, sports, academics, you name it. You were a bit popular because of this, plus you were really handsome. Ryujin was kinda similar in that aspect, also being good at everything. She was especially good at sports, primarily soccer and volleyball. She’s a bit tomboy-ish and feisty, so she’s not scared at all to fight back and stand up for herself. Ryujin was a bit violent too, often threatening you when you got on her nerves. Did she ALWAYS mean her threats? No. But has she gone through with her threats before? Yes, she has.
