It isn't 1 fp it's 5fp. The chapters have increased not just in coins but in fast . passes too. They seem to range from 33-48 coins and 4-5 fast passes.
I enjoy this story but the jump in price is just ouch. Seriously the huge increase in price for these chapters is ridiculous. They aren't 3x's longer to justify that much of an increase. I will only be using fast passes from now on.
I really hope this story gets picked up and continued. This premise is different from other rebirth stories I have read. After reading 60 chapters it would be awful if this became another bone of the stories that isn't finished
