"The Chairperson" and "The Delinquent", two clumsy青春... but that's not all! The entire class's "Yuri" is happening simultaneously!! In a certain girls' high school, Class 2-1 with a decent偏差値. The class of 30 uniquely vibrant students spends their days in a way that is never boring, filled with lively chaos. If you take a closer look at the classroom, you can see the intertwining feelings of each of the 30 students... An academy omnibus volume 1 that watches over a class full of unique "Yuri"!
