Everyone knows that Hyukjae is awkward with Boa.

Everyone knows about Hyukjae's trainee crush. 
Admiration for his same-aged senior in the music industry, his questionable future as a trainee contributed to his lack of self-confidence when love was in question.

Eunhyuk, however, has since given up on his long time crush.

But when they are both assigned to become dance partners for Boa's comeback Only One

Will Eunhyuk like Boa again?
