Mitsuyoshi Tada (voiced by Yuichi Nakamura) is an ordinary second-year high school student whose grandfather runs a coffee shop with the same name as him. Tada's dream is to become a photographer because this is the profession of his late father, and Tada hopes that he can inherit his father's mantle one day. By chance, Tada met Theresa (voiced by Iwami Mai Naka) on the street. Theresa is a blonde and blue-eyed German girl who came to Japan to study. Tada helped Theresa who was lost and separated from her companions, and took her to her grandfather's coffee shop, which made a deep impression on Theresa. After that, Theresa became Tada's classmate, and met Ijuin Kaoru (voiced by Mamoru Miyano), who has a carefree and noisy personality, and Sugimoto Ichi (voiced by Yuichiro Umehara), who didn't know what he was thinking about.
