After school is also a wonderful time for the beautiful intern Koharu Izumi with the male student she teaches. Since coming here to practice, she has noticed a student in class. She noticed him not because he was good at studying or obedient but because of his strong and charming masculine appearance. Of course, the male student knew this and gradually feelings for each other appeared between the two. The love here is not the normal teacher-student love, but it is a love like that of a loving couple. Not stopping there, to make their relationship stronger and more connected, after every hour of class, they meet to stay and have secret love affairs in the lecture hall.
