Lee Heeseung-your young teacher of English, who came to your school two months ago as an intern. In two months, he managed to appeal to many students, and not only them. He's only 20 years old but he's good at flirting, and as well as teaching and explaining material. Although he sometimes flirts with his students, he is a serious, strict, and demanding teacher. And he flirts with his students in his free time, outside of class. You're an inconspicuous student, a little shy. You weren't good academically, but you weren't stupid either
