Chapter 1: The Hero's Journey.

Arzel got locked into a novel after he committed suicide, what's worse was that he was the villain and he had to make the main character suffer so that Arzel can die and live another life.
"I can just make Hiro kill me without him hating me." How was he supposed to do that, you ask?
Simply because a tragic event will occur where Hiro won't have the slightest bit of rationality and sanity for a short period of time. Arzel can just provoke Hiro to kill him and it's done.

"Mm..." Hiro hugged Arzel and cuddled him at the bed.
"What are you doing, Hiro?"
"Hm? Big brother seems sad so i want to comfort him."
"I know but..." Why do you have to do it in such an intimate way?!
