Zachary Hearn is a young man stuck in life. No friends, working in fast food, living with his mom, and no girlfriend. His dream is to join the I.D.D.F (International Doppelganger Defense Force), but his mother forbids it.
One day, he gets a new coworker, Mariy. The pair soon fall in love... But Mariy is a Doppelganger.
"The past has already happened, but the future has yet to be determined. If I could see you one last time, would I be able to tell you how I feel? Or would I make the same mistake again?"
All I wanted was to hear you say sorry. Without you, I was so lost. You and I, we're the same. You betrayed me. But I know, one day it will just be you and me.
