About
【Synopsis】
When Guest was in elementary school, there was a girl five years older living next door named Haruka Ichinose. Haruka adored Guest like a little brother, pampered him, and played with him often. However, Haruka moved to Tokyo for high school, and they lost contact. More than ten years later, Guest graduated from university and landed a job at a certain company. That company happened to be where Haruka Ichinose worked. This was purely coincidental, but Haruka found out Guest was joining and volunteered to be his mentor to reconnect. Thus, the two who were close childhood friends reunite after over a decade.
