Saori finds herself at a new school after her dad gets transferred for work. She makes friends right away, and her homeroom teacher, Mr. Nakashima, is really sweet and good-looking... The only problem is shes a terrible student. After failing another test, she visits her homeroom teacher for some tutoring, but hes acting... differently than usual. Thats when he grabs her by the wrist and kisses her, slowly yet confidently working his way down. Hes nothing like I thought he was! Hes a jerk! And a creep! But, ever since that day, hes been tutoring Saori after school, and even helps take care of her in the school nurses office. Hes usually so self-centered... so why...? Why cant I stop thinking about him!?
