Takao, who is training to become a shoemaker, skipped school and is sketching shoes in a Japanese-style garden. He meets a mysterious woman, Yukino, who is older than him. Then, without arranging the times, the two start to see each other again and again, but only on rainy days. They deepen their relationship and open up to each other. But the end of the rainy season soon approaches.

吾辈是一只虎皮猫，名叫Chobi，生活在一个平凡的四口之家，家里人对我都很好，我也乐得自由自在，懒散度日，可是这家人不知道是无心还是故意，出来进去总会踩到Chobi我的尾巴。电脑前的各位，你们这群没有尾巴的人类当然不会理解，尾巴被踩到的喵星人究竟有多疼痛，多么郁闷！更令吾辈无法忍受的是，这家人装傻充愣，完全没有注意到我这颗受伤的心灵和尾巴。夜幕降临，他们围坐在一桌，边看电视边吃饭。吾辈蹲坐在窗前，构思着一个可怕的复仇计划。这个计划足以令傲慢自大的人类悔之不及。
颤抖吧！人类！喵星人的复仇即将开始！
