Planeta Borboleta paints a dreamy, cosmic landscape where love is a whole new world—or rather, a whole new planet. Mariana Nolasco wonders about the color, the flower, and even the pain that inhabit this distant place where her loved one now hides. Comets crash, butterflies fly away, and violet hues glow, all to illustrate how unique and irreplaceable that shared universe once felt.
Beneath the celestial imagery lies a simple yet powerful feeling: saudade, the deep Brazilian word for longing. The singer misses her partner, misses herself when she was with them, and aches to merge their "planets" once more. The song turns every color, flower, and letter into a keepsake of a love that is far away but still alive in memory—inviting listeners to travel through space and emotion at the same time.
