Because none of the students in Class 0 submitted their admission application form, Kagami Rei (Yamada Ryosuke) was scolded by the dean of students, Dobashi Junpei (Nagano Munenori).Therefore, Kagami asked the students in Class 0 to take the career adaptability diagnostic test that is also used in the Kagami Group's employment test.

That night, Kagami and Serizawa Ichika (Haruka Kinami) asked Teach (Yumi Adachi) to analyze the results of the diagnostic test.Teach said: “I noticed a student——”.

The next day, Kagami and others interviewed Nishitani Sho (Mizusawa Rintaro), Umeno Himika (Uesaka Juri) and others separately to inform them of the results of the diagnostic test.Konno Naoto (Matsuda Genta) tells Kagami that he wants to find a job, but he doesn't know what kind of job he wants to do.

On the other hand, Mitsui Hikaru (Mirai Shida) strongly opposes Kagami's use of career adaptability diagnostic tests to determine the direction of further education.She believes that as long as you adapt to the students' personalities, the future will appear naturally.

However, in front of Mitsui, the graduate Sarina Majima (Haruka Kudo) whom she once taught appeared, and she came to discuss something.Kagami advises Mitsui, who can't even handle it as a graduate, “You are overworked and should reduce your workload”——.

At this time, Serizawa was called by the principal Todo Makiko (Miki Mizuno).Makiko said to Serizawa: %You know everything, right?What happened between Kagami and me——.

Makiko, who knew Kagami's past, finally took action.Those are the secrets that Kagami herself doesn't know, the problems she is about to face in entering higher education, and the students who are growing up in a place where Kagami is not around.All parties are intricately intertwined, and the story accelerates dramatically toward the final stage.
