character: hoshino_aquamarine, hoshino_ruby
hoshino aquamarine, hoshino ruby, create a Japanese anime-style poster themed "Youth Memories and Unspoken Feelings": the core character hoshino ruby stands at a classroom door or in the center of a school corridor, body slightly stiff, hands carefully holding a heart-shaped gift box or themed memento tied with a ribbon and bow, looking up at an important companion who has just appeared, cheeks flushing rapidly, with an expectant, nervous, and earnest expression; the observed companion hoshino aquamarine is located in the left mid-ground, having just entered from behind the door, carrying a school bag on their shoulder, one hand gripping the strap, stopping in their tracks to look back at the core character with a <gentle and slightly confused expression>; all characters wear school uniforms consistent with their settings, based on dark gray or dark green blazers, white shirts, ties or bows, and gray-blue plaid skirts/trousers, with specific hairstyles, genders, and clothing details adjusted according to the subjects.
Several translucent brownish-gold cinematic film strips enter from the edges of the frame, rotating around the characters in large spiral curves: one drops from the top left and crosses the mid-ground, one curves from the top right around the core character's face and shoulders, and one spirals down the body into the foreground before exiting the frame at the bottom left. Each film frame embeds daily memory fragments consistent with the relationship between the subjects, such as walking home together, sports, classroom interactions, walking in the rain, photos with friends, reconciliation after an argument, exchanging small items, or holiday activities; the thumbnail images use different warm and cool tones and various shot sizes, recording the evolution of the relationship like a continuous storyboard. Small text such as posters, notes, and chat boxes within the film should be naturally generated, short, readable, and fitting the scene, without additional title placeholders. Film perforations, transparent bases, frame borders, and reflections remain clear; nearby frames are moderately enlarged with slight motion blur, while distant film narrows into the depth of space, making "fragments of the past replaying around this moment" the most prominent visual signature.
Use a vertical 3:4 dynamic group composition with a slight low-angle wide-angle perspective; the core character occupies the right foreground extending from head to thighs, with the gift box at the central visual focus; the companion on the left is slightly smaller, framed by the open classroom door and lockers. The perspective lines of the door frame, lockers, and walls converge toward the center, forming a stable triangular composition between the characters, while the film curves form continuous rings around the exterior. A large amount of white petals, golden light particles, and slender feather-like sequins fly in the same direction as the film; foreground petals are stretched, blurred, or cropped, making the image feel like a moment frozen at the peak of emotion.
The overall style is high-completion modern Japanese cel-shaded anime illustration, with clean, soft line art using dark brownish-gray instead of pure black; faces, hair, and uniforms use two to three layers of clear color blocks for shaping, eyes retain glass-like highlights, and skin is rendered in creamy white and peach pink to express youthful translucency. The comprehensive color palette revolves around honey gold, apricot orange, creamy white, chestnut brown, dark green, and gray-blue; the background is dyed a warm golden orange by evening backlight, while memories in the film intersperse cyan-blue, grass green, and cherry pink to create temporal layers. Strong sunset light shines from the top left and outside the door, creating dazzling rim light on hair, shoulders, the edges of the gift box, and scattering petals; the core character's face is in a soft, warm penumbra. Add highlight overflow, air dust, shallow depth of field, slight chromatic aberration, soft-focus halos, and fine film grain to create a bright, nostalgic, heart-pounding atmosphere akin to graduation season, the ending of a youth movie, or a turning point of fate. Maintain natural and believable hand-holding of objects, character gaze, overlapping film strips, door frame perspective, and foot weight distribution. Do not use cold/horror tones, realistic photographic skin, heavy oil painting brushstrokes, plastic-feeling 3D rendering, irrelevant titles, signatures, or watermarks.
