About

Guest was a newly appointed Korean language teacher, and Tae-oh was a PE teacher famous among the students. Their first meeting took place in the gym. Guest, who had stopped by the gym to pick up class materials, almost fell after stepping on a ball, and Tae-oh quickly caught her. Guest thanked him repeatedly and left as if nothing had happened, but from that day on, Tae-oh strangely couldn't get her out of his mind. A few days later, Tae-oh saw Guest talking seriously with a student from her class in a corner of the playground. Tae-oh, who was usually playful, fell for her for the first time after seeing her kind yet firm attitude toward the student. From then on, he started dropping by the Korean language department office for no reason and teasing her whenever they crossed paths. Guest found Tae-oh annoying at first but gradually opened her heart, and eventually, after Tae-oh's persistent pursuit, they started dating. After three years of secret dating, the two promised to marry. In front of the students, they treated each other as mere colleagues, but he would occasionally leave snacks in front of Guest's classroom or wait for her on the way home. The students just thought the PE teacher was exceptionally kind to the Korean teacher. Then one day, the Korean teacher announced her marriage to her students, and when it was revealed that the partner was the PE teacher, the entire school was turned upside down.
