"I had a really scarred heart, to be candid with you, growing up," he explained. "I didn't have the greatest childhood. So due to those events, I protected myself and I would never open up or allow people to truly know how I felt so that I wouldn't get hurt."

Now, however, "I'm more affected by the world, by others' pain," Murray continued. "I've kind of taking that scar, and peeled it away so that I can truly love, because there's always got to be a day where you look at yourself in the mirror. And you say, 'Who do I want to be? What do I wanna be?'"
