character: sui_(isekai_ojisan), A single vertical illustration designed as a breathtaking book cover. The composition captures an intimate moment inside the greenhouse at golden hour. Sui sits on a wrought-iron bench, and Alan rests his head gently on her lap, his eyes closed in peaceful trust. The atmosphere is deeply tender,serene, and overflowing with quiet, unconditional love. Ample negative space at the top and bottom is reserved for the title and author name. The greenhouse glows with the warm, honeyed light of golden hour. Sunlight streams through the glass panes, casting soft, geometric patterns and warm light flares across the scene. Climbing ivy and hanging plants frame the edges. Cascades of wisteria in soft lavender and violet drape from above, some strands hanging low enough to brush the scene. The air is hazy with floating golden dust motes and a few drifting wisteria petals. The overall mood is quiet,sacred, and timeless. Sui sits gracefully on the ornate wrought-iron bench, her posture soft and relaxed. She wears her simple, beautiful white sundress with delicate spaghetti straps, the fabric pooling softly around her. Her porcelain skin glows warmly in the golden light, and her jet-black hair, cut neatly to her shoulders with straight bangs, frames her face gently. A single wisteria blossom rests behind her ear. Her dark, expressive eyes gaze down at Alan with overwhelming tenderness. Her expression is one of quiet, devoted love. Her beautiful Cupid's bow lips are curved into a soft, serene smile. Her cheeks are dusted with a warm, gentle blush. One of her hands rests lightly on Alan's hair, her fingers gently stroking the platinum strands. Her other hand rests protectively on his shoulder. Alan lies on his side on the bench, his head resting peacefully on Sui's lap. His body is relaxed, one arm draped gently over the edge of the bench, the other resting near his heart. His pale platinum blonde hair is elegantly styled, swept back from his forehead, but a few soft strands have come loose and fall across his brow. Without his glasses, his face looks younger, more vulnerable, and utterly at peace. His eyes are gently closed, his dark lashes resting softly against his cheeks. His expression is the purest image of trust and serenity — the face of someone who feels completely safe, completely loved. A faint,peaceful, closed-mouth smile graces his lips. He wears his soft cream-colored linen shirt, the fabric slightly rumpled from lying down, sleeves rolled up. His hand closest to Sui rests gently on her knee. The small, slightly imperfect flower crown he made for her now rests on his own chest, held loosely in his fingers, or hangs delicately from her wrist. The focal point is the gentle intimacy of her fingers in his hair and his head resting on her lap. It is a moment of complete, vulnerable trust. Tiny golden sparkles and soft wisteria petals float around them. A single, delicate sunbeam falls directly on them, as if the light itself is blessing the moment. Warm honey-gold, soft lavender,violet,white,cream, platinum blonde, jet black, touches of soft green from the ivy, and glowing amber light. The upper portion features soft wisteria silhouettes and golden light flares, perfect for an elegant title in delicate gold foil or script font. The lower portion frames the couple on the bench, with space for the author name. The overall tone is pure,sacred, heart-achingly beautiful romance — a cover that captures not passion, but something deeper: trust,peace, and the quiet beauty of being completely seen and completely loved.,beautiful light,best shadow, color blink,cinematic lighting,
