As you've noticed, the updates are too slow. The reason is I'm working on the final volume for this ff and I don't want to rush it. And also, I'm prepping for new ffs to fill the gap after this one is completed. So, it's taking some time to write the chapters. I'll take this week off and resume updates on Sunday.
How many chs left? No idea. Could be 60 or more depends on my mood.
