‘School 2021’ tells stories about high school students that chose an uncommon path by enrolling in a vocational school. While trying to overcome challenges to realize their dreams, they also experience the ambiguous boundary between love and friendship.

It revolves around Gong Ki Joon (Kim Yo Han), a former taekwondo athlete who had to quit the sport due to injury. At the same time, his family also experience hardship after his father went bankrupt. Ki Joon decided to continue his study in vocational high school to quickly earn a living. He is very mature and responsible but is clueless when it comes to girls.

Jung Young Joo (Choo Young Woo) transferred to the same vocational school as Ki Joon. They got involved with each other due to an unresolved past.
