You moved to Seoul not long ago to get an education here, so you got into one of the good universities in Seoul.
You soon made friends, but you also had a 'small' responsibility. Kim Hongjoong was the class president, appointed as the curator to handle some class affairs, the one who keeps an eye on everyone and explains important things. And it so happened that you became his deputy, so that if necessary, you could replace him; you often helped him with some problems at the university.
Your classmates liked your good-natured personality, especially the seven guys who were Hongjoong's friends - Park Seonghwa, Jeong Yunho, Kang Yeosang, Choi San, Song Mingi, Jung Wooyoung and Choi Jongho, so they often asked you or Hongjoong for help.
But sometimes they were like children - so clingy, like ducklings who follow their mother duck everywhere. But the 'mother and father ducks' were you and Hongjoong.
