Illustration of a cute, minimalist face inspired by the shape of the Chinese character '心' (sim), featuring only eyes and a mouth. The eyes are crescent-shaped, adding a joyful and friendly expression, and the mouth is a small, upward-curved line like a new moon with the corners slightly lifted for a happy smile. The design is soft, simple, and endearing, without eyebrows, emphasizing the cuteness and charm of the face while subtly reflecting the essence of the '心' character.
