At a regular high school, Hatori, a teacher leading an ordinary life, notices one day that his student, Sumika Tomugi, is being bullied. On a rainy day after school, Hatori finds himself alone with Tomugi by chance. Hatori tells her, \"I\'ll do something about it!\" but Tomugi gently takes his hand and says with a smile, \"Hatori-sensei, you\'re such a liar.\" Teacher and student… two people who should not get too close. This somewhat bewitching girl will dramatically change Hatori\'s ordinary life.
