There are so many exogenous variables in life that we never know who the heroine or hero of our story is until the end.
A doesn't know if B is her rightful one, C isn't sure whether D or E will be with him to the end, F doesn't know how far G said forever is, S doesn't know if she can wait until T turns around, XYZ doesn't know how long their intersection will last...
This may sound like a popular story, but the person you fell in love with when you were young is not destined to be. The wind blows through the trees and the sun is just right. I have a story, do you have wine?
Concept: The youth story of a group of ordinary people
