My name is Shimohei Joutarou. There exists a reason why I'm here, within my new work environment, despite the fact that the college year hasn't started.

On that first day, I presently stumbled on Mitsuki's and Minami's secret. Then i found out about Mahiru, younger sister of Classics teacher Kuji Hinako, as well as the astonishing improvement of her grades. I then discover symptoms of Hinako's backdoor maneuverings.
