Sugiyama, who is passionate about education, is still at the school gate giving life guidance to students coming to school.
Since it was the day before winter break, he was more enthusiastic than usual in his teaching.
Yoshizawa is a gal who doesn't care about Sugiyama's guidance, but she is made to change from her uniform skirt, which is too short, to a jersey, which is against school rules. Yoshizawa sulks.
Sugiyama tells Yoshizawa that he is teaching him for Yoshizawa's sake, but it is a wasted effort.
On the day of winter vacation, which is filled with worries about his poor teaching style, Sugiyama plans to call a delivery health service and enjoy some slippery play with lotion.
However, the girl in uniform who appeared was his student Yoshizawa.
Sugiyama tries to get her to go home, but Yoshizawa takes a two-shot photo of her in her underwear, leaving him unable to change clothes.
