Chapter 1 – Samey (Complete) 

Girlfriend have grown tired of her father’s many attempts to get her beloved Boyfriend killed by mercenaries, tankmen, his wife and even himself. So Girlfriend decided to take a little vacation off town just so her family won’t interfere, and finally have some lone time with her Boyfriend. But little did she know that she picked one of the worst places to stay on.

The time has come at last.

The couple arrive at a place called “Voodone St.” where they’d go into an empty parking building. It is said that this parking building have been locked down to unknown reasons, which made it the perfect place to hang around on… Until GF starts to hear the sound of crying comin’ nearby.

A specimen with the name of “Samey” happen to lurk around the empty parking building only to take care of his own inner demons.

GF suggests that they could calm him down with some soothing music! What could possibly go wrong?
