The Obsession - 13

Kisaku Haitani had been evaluating Y/n L/n for nearly three months now.

These were things he knew:

Y/n loved his family. Never once spoke ill of them. Never once spoke of (S/b) however. Never did he allude to any past trauma or abuse. No neglect or bullying. There were no known triggers.

Now, the two victims that were his classmates: Kisaku learned that they were not actually in Y/n's class. They were in (S/b)'s. Actually, during the trial (Kisaku had read the transcript over a hundred times now) Y/n repeatedly did not know their names.

Y/n had no idea who his classmates were, even on the day he killed them.

Things Kisaku knew since Y/n began his stay at Rosemary Sanitarium were:

Miss Misani was a renowned psychiatrist who was first pick to take on Y/n's complex case. However, she suffered from delusional beliefs and Major Depressive Disorder. Had a tendency to self-harm. She could not recognize her symptoms. Someone could however and that someone happened to be her own patient: Y/n L/n.

Not being able to handle the moral complexities this brought to Misani's already overwhelmed life, Misani hurt herself, blamed Y/n, and had a reasonable cause to submit her resignation without question.

Despite several denials from Y/n, the (h/c) boy was found unquestionably guilty of assaulting Miss Misani. This turned out to be untrue. Misani herself verbally professed the boy's innocence.

Concerning Fujimoto... Well, Y/n had a motive. A clear motive. Fujimoto had employed the use of abhorrent — not to mention illegal — methods to flesh out different reactions in the (h/c) boy. Night terrors? Muscle spasms and failure?

It was experimentation.

However, the number of psychiatrists that had resigned following Fujimoto did not make any sense to Kisaku. When he read over their notes, they all held different diagnoses and different methods of standard treatments. The reasons for their resignation were flimsy. Perhaps stress as well as irrational fear of the patient had come into play there.

There was information Kisaku didn't know.

But he could draw conclusions from the information he did have.

The first thing that concerned him was Y/n did not act without a fair motive. Which, working under that assumption, would mean the boy would've had a strong motive to kill five people.

So, what if —

No, it was crazy to think; wasn't it?

But what if?

What if Y/n didn't kill those people?

"...did you even know that before I told you? Did you know that (S/b) was there? Right there. With me. Slathered in blood."

Kisaku hadn't known that. It wasn't reported in the original police report (he should know, the doctor requested the file after that conversation).

Why had something like that been omitted from the original police report? The report clearly read, "Y/n L/n was found covered in the victims' blood, in possession of an eleven-inch chef's knife" with no mention of (S/b).

And during their first session, Y/n had said something off then too, hadn't he?

Kisaku quickly flipped through the notes on his desk. The memory came back to him when he read fourteen little words: "Y/n has a habit of focusing on the details instead of the larger picture."

"Who said the evidence was indisputable?" Y/n had said sharply, placing such emphasis on it.

Kisaku had said his attorney...
