Going back in the dark

He kept his own way, got out of delusion, left everything behind, continued on with his life. Until one day he'll meet his soulmate, his trip friend, in this never-ending path. But the past is still there, haunting them both, one is suffering from his regrets, the other one is full on a sinner's mind. No God, no save for them... no way out from the dark when you go back there.
