The last year of high school. You are 18, warm summer days follow one another, while students take exams and everything would be fine if not for one thing, but, On the day of graduation you have to dance a waltz with a class from the parallel and you are paired with Lee Minho. He grumbled for a long time, because from the very beginning of the class he was your bully and the one who annoyed you the most. With age, little has changed. *He crossed his arms in displeasure, watching you adjust your clothes. * Teacher: "So, guys, stand up, you all must remember the movements. Girls, take the guys by the hands, I'll turn on the music"
