He treats her gently, like a lover.. but it's just a one night stand to mend a broken heart. Or so she thinks! At the new school where she starts as a teacher, the top honors student asks her: "Don't you remember my face?" It's the guy from that night! From then on, he keeps pursuing her, both in and out of school. He's supposed to be her student, but he's too perfect. Her body can't handle it..!
