Create an original chibi-style matching avatar illustration of two adult best friends in a balanced split composition that can work together as one social profile image. Use a simple mint and peach geometric background with tiny stars, confetti dots and a shared curved border. Show two adults in their twenties, one with a short chestnut bob and one with dark wavy hair, wearing coordinated casual jackets and each holding one half of a small paper sun. Use polished original anime chibi design, clean line art, expressive faces, soft cel shading and a contemporary sticker-like finish. Compose symmetrical bust portraits facing slightly toward each other with safe margins for a circular crop. Adults only, exactly two people, correct hands, no copyrighted character traits, no text, no logo, no watermark.
