ฟองสบู่เหลือบสีรุ้งพร้อมอักษรวิจิตรภาษาญี่ปุ่น

A dreamy minimalist square photograph of a single iridescent soap bubble floating centered against a deep blue soft-focus background. Bright natural sunlight streams from the upper left, casting delicate lens flare, circular bokeh, and luminous highlights. The central bubble is sharply detailed with swirling rainbow reflections and a tiny star sparkle along its lower right rim. Six blurred companion bubbles frame the scene: one large partial bubble at the lower left corner, one small bubble near the upper center, one faint bubble at mid-left, and a soft glowing cluster of three bubbles along the lower right. Overlaid across the center is expressive, handwritten Japanese brush calligraphy in white ink reading "[はじける泡。]" with organic, uneven ink texture and poetic spacing. Airy, luminous, nostalgic mood with shallow depth of field.
