A ten-year old Japanese schoolgirl named Shinobu Omiya has a homestay visit in England, where she spends time living with a British girl named Alice Cartalet. Alice initially has trouble getting along with Shinobu due to the language barrier, but they soon get along swimmingly. As Shinobu's homestay comes to an end, Alice hopes that she will one day come to Japan. Five years later, Shinobu, who is now in high school, receives a letter from Alice, allegedly saying that she is coming to Japan. Surely enough, Alice appears at Shinobu's school, revealing she has transferred to her class and will be staying at her house.
