The film is about the time when student teacher Yui Hatano had happy moments with her students and colleagues at an unpopular high school in the countryside of Shirakawa, Japan. First, Hatano took the initiative to forget a particular male student in class. She called him to her private room and began to talk about studying. Of course, after only a short time, both of them began to move on to other "things", this story was much more attractive and appealing than studying. Not stopping there, Yui Hatano continued to "talk socially" with her physical education colleague in... a private room, where only two people could "talk" to each other without anyone "eavesdropping." "(meaning here is disturbed.) And finally, she switched to playing some, using "2 guns" alone, not knowing if Hanato could handle it or not :)).
