Produce 101 boarding school is a combine of high school and university, where students are trained in preparation for their future career. The school ranks students based on academic and talent where top 11 students get a dorm to themselves, but this year they have to share a dorm with another because more students are accepted in. When the girls first entered the school as top 11, the other students called them IOI. As they were role models for the other students but they didn't know each other very well except for a few who made friends with each other during their entrance ceremony.

The main characters would be of course IOI members, it would be where our main couple who hate each other and fall in love with each other. WHat would be the accident that happen in between them?
