Pink-haired fairy holding phone

A wide-format digital illustration of a beautiful anime-style fairy with long pink hair and black-rimmed glasses, holding a smartphone towards the viewer. The phone screen displays an anonymous confession interface: 'send me anonymous confessions! on...' followed by the message 'you're the most beautiful blue butterfly' and a reply 'The mighty blue monarch~!', with the logo 'UNSAID' at the bottom. The character has large, translucent wings with intricate blue and purple patterns resembling stained glass or butterfly wings. She wears a dark, frilly outfit with ribbons and a choker. The background is a magical, ethereal scene filled with glowing blue butterflies, hanging crystal ornaments, and faint mathematical formulas floating in the air.
