i did not get any of this omg am i slow

In simpler terms, big writer dude made stories inspired by the little guys he assaulted and killed (yuck). Big writer dude dies and reincarnated, and so did all the little dudes. Big dude stopped aging after reincarnation and is old asf. Little dudes post reincarnation all “kill” big dude for revenge until the last one, mc, manages to actually kill him (and himself), who was the reincarnation of the 8th(?) victim. unsure if they actually loved each other but I think there’s a better word to describe their twisted attachments. Very supernatural but easy to grasp. I left out a few details tho
