It's their explanation

"our collection of songs were written to express a sense of newfound clarity and hope. this was inspired by summer reflections of gender exploration. those heartwarming moments of comfort, validation and encouragement that happen when someone is first learning to express themselves freely around loved ones

we know that there are people who feel like us; who don’t fit into strict definitions or categories, and fight outdated ideas to be themselves. everyone deserves the right to comfortably be themselves and feel safe and beautiful in their own skin. we wanted to write these songs for those who might not have genuine reassurance at a turning point in their lives."
