Do not worry, my friend. The reserved chapters are mostly r-18 and do not affect the main story progression in any sense. They are only for fun and that's all. I just don't release some chapters to not offend any audience since some chapters include a heavy theme that might not suit the general audience. But that also does not mean that you cannot read them for free since only the future chapters are reserved but for the first two volumes, these chapters are accessible for the free members...
