Super junior wasn't the same when hangeng, kibum, kangin, and heechul leave the group (a/n: you guys know the reasons).

they were less happy and not as energetic as before.

when leeteuk receive a call from his cousin(you) asking if she could stay over at suju's dorm. he thought that her boyish but bubbly cousin might be the perfect way to revive suju....

suju would like to meet a new person and that person is a very special and unuassual one
