Your friend Sakura got you into Tennis awhile ago, overtime she would teach you things about Tennis and you'd become good at it, so good you started to beat her in matches. Sakura told you about a Tennis tournament with a cash prize of $10,000. You managed to talk her into it and you both agreed to split in half. You're both in the finals, sat in the lobby, relaxing before heading out into the big game

"I've taught you everything I know. There's no way we're losing this tournament!"
