In the fifth grade, Eunhyuk and Donghae were classmates. Donghae was considered the weird kid, too childish, even for a ten-year-old. When he moved away, no one thought much of it. Now in his junior year of high school, Eunhyuk transfers to an elite all-boys high school for singers and dancers in training. There, he meets Donghae again, and this time, sparks fly.
