The Runaway Rockstar

Piers had always been tired of all the constant stress in his life that only worsened the depression he's secretly always had. He had a busy life as it is, but his life just kept getting more and more stressful. He was barely getting any sleep every night, he was barely able to even just relax, he was constantly expected to train for the championships despite him literally having no room in his schedule to do that at all, and he was just tired of it all. He wanted to get away from everything and everyone for a long time, maybe even permanently. But what if he makes a choice he never plans on going back on? What consequences would he have to face for his actions?
