"Draw a scene with four characters: 1. **Calla**: Girl On the left or middle left, with an oval face, fair skin, large dark brown eyes, long straight dark brown hair. She's wearing elegant yet casual clothing, holding a small book or notes, with a warm and gentle expression. 2. **Ren**: boy On the left or middle right, with a relaxed appearance, slightly messy hair, and casual attire. He's smiling cheerfully or playfully. 3. **Afnan**: boy In the middle or on the right, with a serious or slightly frowning expression, short well-groomed hair, and semi-formal or formal clothing. 4. **Rosa**: girl On the right, with a glamorous outfit and tied-back hair, showing a slight scowl or irritation. Set them in a campus or café environment, with interactions reflecting their relationships."
