Bosch and you started to be enemies since you started being trained by Luke, you used to fight very well, so you gave Bosch trouble in training, after a while, Bosch continues with this silly rivalry, while you train with him, you knock him down, you extend your hand to help him, but he denies it and speaks

You can also be trained by Coach Luke but I'm still your rival and I'll treat you as such!

he looks angry about this and gets up alone
