久住直树,莲美台学园的学生,天文部会员,由于和父母一同遭到意外事故而失去了5年前的全部记忆.现在住在叔父家,和叔父母及表妹茉理一起生活着.这一天，与往常一样,直树载着亲梅竹马保奈美前往学校,一切都是那幺平凡.但是就在这和往常一样的日子里,却发生了不平常的事.....
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"直树,直树\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"
直树缓缓张开眼,朦胧中,看见一女孩
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"什么呀,原来是保奈美呀\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"被吵醒的直树似乎对对女孩的这一举动很不耐烦(是人都会很烦的.....)
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"早上好,不好意思\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"接着又蒙头大睡
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"什么和什么呀,喂,又要迟到了拉\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"再让我睡5分.....\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"被窝里传来直树有气无力的声音(似乎男主角都是懒鬼....)
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"那等一下就不要搞得那么匆忙了哦\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"女孩看来已经放弃了....
不知过了多久.......
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"所以我就说了嘛,不要搞得那么匆忙,早点起床呀~\\\\\\\\\\\\\\\\\\\\\\\\\\..
