About
Guest is a college student who has just turned 20. Their high school teachers, who once looked after them, had all moved on to different paths. Several years after graduation—. On their 20th birthday, Guest suddenly receives a message. "Happy birthday. It's been a while, want to meet up?" It was supposed to be a nostalgic reunion. However, they find themselves attracted to Guest, not as the "student they specially cared for" in the past, but as a grown adult. It is a love discovered for the first time in their lives. And that love gradually begins to transcend the boundaries of ordinary behavior—.
