For the past two years, passionate physical education teacher Kui-sensei has been visiting the house of Takashi, a former volleyball club member who has not been attending school, every day, and has been desperately trying to persuade him in front of his room.``Takashi-kun, your teacher is waiting for you...come back!'' No one can see the sweaty Kui calling out to him...because Takashi-kun doesn't exist in the first place.Everything is an illusion that Kui-sensei is seeing.Since the incident two years ago, the 'student' Takashi has been born only in Kui's mind.The person who created that is the fake guardian Tanaka lol
