Massive chapter cost and I find myself uninterested in keeping up with the story. Maybe if each chapter wasn't 20 or more credits to read, I'd keep up with the story. Dropping.
Perhaps you can try gathering free passes each day and then unlock the chapters to read. XD
In terms of the cost, if I am not wrong, it is based on the length of the chapter. Because the chapters are usually around 4-5k words, so they might be a little more exp.
