Review Detail of LonelySpine in illicit relationship

When I started reading this book then, I thought it's a book that won't last and just stop before reaching a thousand chapters, similar to other books. Fortunately, the author proof me wrong and the book gets more interesting as it cross the thousand. @ author, since we reached the last volume, how many chapters should we be expecting more before the book finally gets it's ending? How does the affect the mc and his harem? Would it be similar to other books that just rush to finish the book or will you proof me wrong again, unlike others, that this book will have a befitting ending.
