Rosé discusses the creation of her solo album 'Rosie', which serves as a personal diary exploring the gap between her public persona and private self. She recounts her unexpected journey from Australia to becoming a YG Entertainment trainee, describing the grueling daily schedule from 9:30 AM to 2 AM and the fear of failure that drove her. Rosé reflects on the immense pressure of being a 'perfect girl' for fans during her Blackpink years and the challenge of breaking away from that culture to write about normal experiences like heartache. She reveals the therapeutic process behind writing 'Number One Girl' after a night of reading negative comments, using songwriting as a mental health outlet. Rosé also discusses Blackpink's decision to pursue solo projects while staying together, and credits her father's advice and her intense training for revealing her determination without changing her core personality.
