Love Apartment: Universal Girlfriend

I don't know if there are any novice authors who have written 8,000 words and feel very satisfied. When I first wrote it, I was bored and didn't want to leave any regrets for my youth, so I opened this book. So sometimes it's hard to worry too much about writing. Also, I want to follow the plot, or write more of my own stuff. If I follow the plot, I will change the plot after writing a certain chapter, and then try not to demolish the apartment. If it were not written according to the plot, I would write more of my own stuff, and then I would simply omit some of the plot. It is recommended to follow the plot, because you won't be confused while watching it, and it won't be too confusing later on. I don't know if anyone has read my book.

Why does the author divide each chapter into a volume?
