Yesung, a member of the newly debuted group, is known to be quite reserved and introspective and he finds Kyuhyun, the newest and youngest member, to be a bit of a nuisance at first, even if he's cute. Ironically both Yesung and Kyuhyun have developed feelings for each other, but they are afraid of damaging their bond so they just settled with dancing around their feelings and hide behind the hyung-dongsaeng facade. How will things go between them when Kyuhyun finally decides to take a leap of faith?
