Ever since that day his friend got shot, Tyler Joseph wasn't the same. He stopped interacting with friends and family, he became angrier, couldn't sleep, and, of course, he couldn't stop thinking of that day. He soon realizes that his actions are having a bad effect on his family, and he wants to change it, it's just he doesn't know how to. Just because Tyler doesn't know how to change it doesn't mean that Josh Dun doesn't know.
