Illustration of a cute, minimalist plush toy character inspired by the shape of the Chinese character '心' (sim). The character has only eyes and a mouth, with crescent-shaped eyes for a friendly expression, and a small, upward-curved smile where only the right corner is slightly lifted. The design includes a soft, round body resembling a plush toy with simple clothing, no hair, and an endearing, cozy appearance. The style emphasizes cuteness and charm, capturing the gentle essence of the '心' character.
