Wheein is a tiny yellow duckling that keeps being teased by the new cat from the neighbor. Her owner loves animals and the human has a female macau ( Hyejin) and a female dog( Yongsun). Both will get very angry and plan to punish the cat. But a turn of events will surprise that small group.  

A Poetic One-Shot (Ballad) about Irene as a bunny, and Seulgi as a bear. Kinda like a children's story/poem?

The five boys who grew up together-- so loyal and so faithful to each other-- always thought they'd be together forever. Their innocent and naiive prospects kept them together for such a long time, but little did they know that soon they would be faced by the determining decisions of their lives. SM was the organization which trained the children to stay with their set pathways or diverge toward an individualized life of their own. These five grew up to face Thd Purple Line.
