Taecyeon and Chansung are childhood friends. They want to be friends forever, however... things change.   

Wooyoung receives an ultimatum.

Hwang Chansung was just a regular dance student at Allegro Institute of Fine Arts, until one day his life changed. And that’s when he met Lee Junho, the most brilliant ballet dancer of the school and part of the meanest clique of their college.

When 2PM members went to the military one by one, they never thought they wouldn't get back together as a band anymore. A scandal, secrets, fights and different dreams set them in a distinct path, but one of them is going to bring the family back together. However it's not going to be an easy task dealing with marriage, mysterious members and successful and hesitant pop stars. But whatever the costs, he will make them one once again.    

Taecyeon is a military kid and has changed schools a few times. Even though is always on the move, he's anxious and nervous about his first day. But everything falls into place when he meets Chansung, a caring person who can see people's hearts despite his condition.
