Just days before, Bieber wrote to his fans explaining that he would return to music afterrepairing some of his “deep-rooted issues”in treatment.

“So I read a lot of messages saying that you want an album .. I’ve toured my whole teenage life, and early 20s, I realized and as you guys probably saw I was unhappy last tour and I don’t deserve that and you don’t deserve that,” he wrote. “You pay money to come and have a lively energetic fun light concert and I was unable emotionally to give you that near the end of the tour.”

Bieber also noted that prioritizing his mental health came from the desire to “sustain” his marriage to Baldwin and live up to the expectations he had created for himself as a future father.
