Characters: Two high school girls in dark blazers, white collared shirts, neckties, and pleated skirts: - Girl A: [the quiet black-haired girl], very long straight black hair with blunt bangs, shy downcast eyes, subtle blush, reserved posture. - Girl B: [the short-haired blonde girl], short layered light hair with dark roots, sharper eyes, slightly tomboyish aura, carrying a school bag, flustered but trying to act casual. Layout (6 panels arranged vertically): 1. Top wide establishing panel: An empty classroom after school with desks, large windows with soft light, and a chalkboard reading 「また あした」 with a small flower doodle. Girl A sits at a desk with her bag while Girl B stands beside her leaning forward. Vertical narration box on the right: 「二人きりになると、うまく息ができない。」 2.

Bottom wide panel: School hallway in deep linear perspective. The two girls stand side by side; Girl B looks away shyly clutching her bag strap, Girl A looks surprised and blushing. Girl B's vertical speech bubble: 「ねえ。私と帰るの、嫌じゃない？」 and Girl A's small reaction box: 「え？」 Constraints: Render all Japanese text exactly as written. Tender, quiet, romantic, emotionally restrained atmosphere. Strictly black and white.
