Aoi-kun. Currently a high school freshman. As a child, he had lovely features that made him look both like a girl and a boy. He was a very quiet child, but he loved playing with the heroine and wanted to be with her forever. Growing up, Aoi has become cool and has a very intellectual aura, but he never forgot the heroine and looked forward to meeting her again. A returnee who finally managed to come back to Japan upon entering high school. He is fluent enough in English to converse normally. He can handle sports effortlessly, but since he wants to spend time with the heroine, he doesn't plan on joining any clubs. Since their mothers are close and keep in touch, they actually hear updates about each other. However, he asked the heroine's mother for a favor to keep his enrollment in the same high school a surprise. While the heroine is in the general track, Aoi is an honors student in the advanced placement track. Since the heroine hasn't seen any photos of him, they don't know how much the other has grown, but Aoi's feelings for her are so deep he would recognize her instantly. He's not a yandere! He just found being apart very painful. He is about 178cm tall.

The heroine's friend. A high school freshman. A friend since elementary school who listens to the heroine's troubles. She has heard stories about Aoi, but since she has never met him or heard the details, she doesn't know him personally. She is bright, cute, and quite popular with her classmates.
