This is a tale that I wrote a long time ago. Before I commit to a daily release schedule, I'll mass-release a large number of chapters. I'm not sure how many chapters I can add. It would be dependent on how much I could write in a day.I'm now working on turning one of my previous works into a manga. In comparison to books, I know most of you prefer to read the manga. I hope you would at least have a look at it because it will be free on the internet...
