Sirens filled the area as more police cars arrived to the scene, an accident has occured. After a tragic car accident, a young man confirmed to be named "Kim Seokjin" was announced dead at the crash site. Hearing the news of their best friend's death, the remaining 6 live to tell their stories that intertwined their relationship with Jin and his death. The 6 boys, Hoseok, Taehyung, Namjoon, Jungkook, Yoongi, and Jimin, continue to break apart and suffer as the memories from their pasts continue to linger and haunt them every second they breathe. They all recall the horrible sins they have done and try to escape them by committing suicide, one by one. This is the act they call the "Butterfly Effect". How one's death affects not only one, but all. Who will remain in the dark past and who will realize reality and live their life while it lasts?
As for they, cannot be "Young Forever".
