Create a vertical 9:16 premium anime-style illustration in bright summer daylight, set in a lush urban flower garden beside a modern tram or bus stop. Two cheerful cartoon children with rounded, simple line-art faces are the main subjects: {argument name="boy character name" default="Masaharu"}, a blond boy with no glasses, wearing a plain white long-sleeve shirt, blue pants, and white sneakers, crouching among the flowers with one hand near his chin and smiling as he looks down; and {argument name="girl character name" default="Momoka"}, a blond girl wearing a pink-and-cream baseball cap, round glasses, a white long-sleeve shirt, pink overalls, and white shoes, standing beside him and pointing excitedly toward a flower. Keep their designs consistent and cute, like official character-sheet cartoon children, with oversized heads, simple eyes, soft outlines, and expressive happy faces. The foreground is packed with abundant colorful flowers, including exactly these prominent flower groups: 1 large sunflower at lower left, pink hydrangea clusters, purple daisies, white daisies, red-orange zinnias, yellow-orange blossoms, blue small flowers, and blurred pink/purple flowers at the bottom edge for depth. In the lower right foreground, include exactly 5 art-and-picnic objects: 1 tilted digital drawing tablet on a stand showing a colorful anime girl illustration, 1 black stylus resting beside it, 1 open spiral sketchbook showing cute flower and character doodles, 1 pencil laid across the sketchbook, and 1 yellow backpack next to a green basket containing water bottles. In the background, show a clean city transit shelter with a tram or bus partially visible, a blue transit sign, leafy green trees, distant high-rise buildings, a tall streetlamp, sunbeams streaming from the upper right, and soft bokeh. Use saturated colors, crisp character lines, painterly detailed environment, cinematic depth of field, warm highlights, TikTok trailer energy, wholesome discovery mood, 720p vertical composition. Avoid text overlays, avoid logos, avoid extra characters, and ensure Masaharu never wears glasses.
