Hyunjin. Hyunlix.

Hwang Hyun-jin, 30, is the school's principal. Lee Felix, 26, is a young teacher.

Hwang Hyun Jin and Lee Felix are the best couple everyone knows about. They never showed it at school because it's not appropriate in a school setting.

Felix is ​​a young biology teacher who's been pursued by a new 11th-grade student named Jisung. He constantly stares at Felix during class, giving him chocolates, toys, and cards.

So Jisung, instead of drawing the chart Felix asked him to draw, forgot himself again and instead wrote, "I love you." Naturally, Felix was in complete shock, so he took him to the Principal. To Hyunjin.

Felix walked into the office with the student and told him to sit in front of the Principal. He sat down next to him, looking at Hwang. Hyunjin's gaze shifted to the student, his expression cold and distant. Hyunjin adjusted his glasses, putting the papers aside. "What happened this time?"
