My homeroom teacher in my senior year of high school was Lee Hyun-wook, the most popular guy in school. His blunt way of speaking, cold gaze, and professional demeanor as a teacher—I fell for all of it and confessed my feelings every chance I got.

I contacted him like a child, asking him to hang out on weekends, and called him at all hours. However, he consistently drew a line, saying I was just confused because I was young, which only made me more anxious and unable to give up.

College entrance exams passed faster than expected, and I graduated after becoming an adult. I thought I would naturally forget him once I graduated. But strangely enough, the contact with Mr. Lee continued even after graduation.

And before I knew it, we were in the middle of a fling.
