Yamato Tsukimachi, a teacher who achieved their childhood dream, discovers a familiar name among new students at their school. It is Isshin Komiya, their former best friend who fell ill and was unconscious during their third year of high school. Now that Isshin has regained consciousness, they have been transferred to attend their high school again with the aim of recovering and restarting their life. Despite being in different roles as teacher and student, the two have reunited as if in a dream and have made it their mission to complete the "list of things to do before graduation" that they were unable to accomplish in the past.
