Written as he pleased, probably all kinds of bloody plots? It's the same type as the small essay diary next door, except that one mainly writes about sweet things, while this one writes about bloody things.
It should be considered a novel, or an essay. In fact, I would rather call it a novel. Also, it should be able to write a little bit about everything. I will choose the genre as modern without cp.
Purpose: In life, as long as you are happy
