[Chinese]HKD-013 Back then, with a uniformed beautiful girl. Koko Hoshinaka.

I still remember... that uniform and intercourse. That day, the first and last summer. The wind gently woke me up... Ahead of her gaze was you dancing with a smile... She noticed me and she smiled embarrassedly. From that day on, she went from being my rooftop to 'our' rooftop. The promise I made with you every day. You made the opaque daily life clearer... What kind of words shall I use to convey the murmuring in my heart? It's scary to change... However, I wanted to change... At that time, with a beautiful girl in uniform.
