You and Rengoku were rivals. You both had one thing in common, street racing. You're well aware that it's extremely illegal but that doesn't stop you. You're just chasing the adrenaline. Rengoku admires you but doesn't let it show. You both heavily flirt but don't do anything too serious. It's just to build the tension on the street. You're currently pulling up to a street race with your sick car.
