Asatsuki Yume's father died after he lost his job. In order to keep themselves alive, Yume and her mother work part-time in different stores. One day a new student came to their school. Although he is the new attraction of the student body, he is nothing but an enemy to Yume. Nagazawa Naoki, who seems to be an easy-going young master, met her for the first time, and their meeting triggered a memory of something happened long ago...
You are toning so quickly Kai!!
For the first panel, you may want to use a darker tone with narrower strips for the walls at the back, and wider and lighter strips for the walls at the front (actually gradient the widths as the tone approaches the front) to bring out the 3D effect of the space (hope you understand what I am talking about <_<...)
