Yang Seungho and Jung Byunghee were the two coolest kids in school. Everyone either loved them or absolutely despised them.  Most of those who loved them were fan girls and those who despised them were the other boys, but one boy was amongst the fangirls--secretly, until one day when that secret is leaked.

Park Sanghyun and Bang Cheolyong have been best friends since second grade when a clumsily little Cheolyong spilled grape juice on Sanghyun...long story short, after a little while, the two became inseparable.

(Don't worry little ones, Joonie will come in a little later, but for now, he is just another acquaintance of Thunder and Mir)
