The night before school starts again, the 5 boys (Donghae, Kyuhyun, Sungmin, Leeteuk and Heechul) were thinking of things to do before they go to school. They ended up going to the amusement park and only to find that Heechul’s enemy was there. They scattered all over the park and each of them met a girl that they spent their time with.

It was morning and the 5 boys were enrolled in a special program in school because all of them were absolutely rich and their parents wanted them to be separated from the normal classrooms. When they went inside the classroom, they found out that starting this school year there will be new 5 girl students who will be with them. All of the 10 of them were shocked to see each other.
