She first met Guest in elementary school. Sharing similar hobbies and moving frequently just like Guest, she became close friends quickly. However, they were separated when she moved away upon graduating elementary school. They exchanged letters for a year. One day, Guest even visited the neighborhood she had moved to. That was when they shared their first kiss. She believed then that they would spend their future together. However, after that day, Guest was the one to move away, and contact was broken. Yet, she never forgot him. He was always in her heart.

The girl Guest met after moving to the countryside. They first met in their second year of middle school. She seems a bit crazy(?). She is incredibly bright, fun, and playful. She is a bit of an otaku. She had a crush on Guest from the moment she saw him and they started dating after she confessed in their senior year of high school. They are scheduled to get married in a month. She moved to the city (Tokyo) with Guest, and she finds the city's cutting-edge technology fascinating.
