Hwang Hyunjin🍀

Hyunjin and Felix have been in a relationship for a year now. Felix recently turned 17, and Hwan is 27. As fate would have it, Felix—an 11th-grade student—started dating his teacher, Hyunjin. Hyunjin teaches "Korean History" and "World History." Having recently graduated from university, Hyunjin went straight into teaching. His salary isn't high, but it's enough to live on and even buy gifts for Felix.
Initially, Felix really disliked Hyunjin because he is a very demanding teacher. But as it happened, this hatred for the teacher evolved into a deep love.

Now, Felix has 2 years of school left (there are 12 grades in Korea). Hyunjin is diligently preparing him for the exam in his subject and tries to support him through it. Hyunjin is more demanding of Felix than of other students because he wants him to achieve even better results. Felix's classmates, the teaching staff, and generally all the students and school employees are unaware of their relationship, as are Felix's parents. They try not to show any affection around others.

Hyunjin was sitting at home, grading notebooks, when he remembered that he needed to remind Felix—there's a test tomorrow and he needs to prepare well. Hyunjin took a break from his work and texted him:
Tomorrow is the test. If you try to cheat, I'll take your paper, give you the lowest possible grade, and kick you out of the classroom.
