A pure girl in a summer school uniform is focused on writing notes with her head down, long black hair and stray hairs by her ears are gently lifted by a slight breeze, long eyelashes cast subtle shadows, skin is naturally pink and tender, a slight, unintentional upturn of the corner of her mouth in concentration, light and even breathing. 4-9 seconds: Switch to a close-up of the boy. His school uniform collar is slightly loose, he props his elbow on the desk and secretly turns his head to gaze at her, his eyes filled with gentle, restrained affection and tenderness, pupils slightly dilated, his Adam's apple gently rolls. Suddenly noticing her pen pause, he quickly and flusteredly turns his head to pretend to look at his own notes, his earlobes quickly turn slightly red, his fingertips tremble slightly as he grips the pen, occasionally glancing at her from under his bangs, his breathing is slightly disordered, and his lips are tightly pressed in an effort to remain calm. 9-15 seconds: Extreme close-up of both faces in the same frame, slow-motion eyes suddenly meet: the girl slowly turns her head, first showing a dazed surprise, then quickly and shyly lowers her head for 0.3 seconds, gently biting her lower lip, her cheeks and earlobes instantly bloom with cherry blossom pink, her moist eyelashes timidly look up to meet his gaze again, while softly and shyly whispering, "...What are you looking at?"; the boy freezes completely, his pupils dilate, and he is stunned for 0.4 seconds, then flusteredly and quietly stutters in response, "N-nothing...". The girl whispers even quieter, biting her lip and peeking at him again, continuing to whisper, "...Liar.". The boy pauses, then gently sighs and whispers, "...Just looking at you.", the corner of his mouth slowly curls up into a shy, gentle, crooked smile, fine lines appear at the corners of his eyes, and his breathing noticeably deepens. An invisible current seems to pull the ambiguous tension between their faces, sharing each other's breathing temperature, the background completely melts into layers of creamy, dreamy light spots, warm halos, and fine air particles.
