A/N: Hope you enjoy it.

Ishimaru Masato is a mysterious boy, people would spread rumors about him. Saying he was an experiment of a mad scientist, he never bothered anyone though. He kept to himself, (Y/N) (L/N) was different though. She was popular and good with everyone. Ishimaru secretly crushed on (Y/N), he felt thay any guy that came too close for comfort was trying to steal her away from him.

Masato followed (L/N) home again, she was perfect in everyway to him. While following (Y/N), another guy came up to her and wrapped his arm around her shoulder. Masato's eye twitched at the sight of them, he then began to lean in trying to kiss (Y/N). Thats when Ishimaru snapped, he continued following the two until (y/n) reached her apartment and went inside leaving the boy outside and her stalker as well.

Ishimaru pulled out a gun, running full force hitting the boy in the head with the handle. He dragged his body to the basement and began torturing him, cutting off his fingers one by one, skinning him like peeling a potato. The torture just got worse as time passed, making the boy eat his on flesh, nailing his hands and feet to the wooden chair. Blood covered his face and the floor, of course blood splattered on Masato as well. The boy was clinging to life as it was being takeb from him. For the final part, Masato ripped the boy's heart out of his chest. Blood dripping from the slightly pumping heart, the boy's eyes still widened. Blood pooling around him, Masato wrapped up the heart and slipped into (l/n)'s apartment.

(Y/n) came out of the bathroom to see the present with a note attached.

'This is my present to you, Please treasure it.'

Unwrapping the present, (y/n) screamed at the sight almost about to vomit at the blood. (Y/n) dropped the box containing the heart, causing it to fall onto the floor. (Y/n) slowly backed up into something, then turning around to find Masato standing there with blood splattered all over his body. He hugged (l/n) whispering into her ear.

"Do you like the present? I did it just for you."

"M-masato? Wha....what did you do?"

"That boy was in the way of me getting close to you. He had to be dealt with."

"You....killed...him?"

"I did for you, love."

(Y/n) screamed and pushed Ishimaru away and ran to her room, locking the door. Ishimaru banged on the door constantly until he stopped, after a few minutes he stabbed the door. Soon, breaking the door down and pinning (y/n) to the bed.

"You're mine, (y/n). Now and forever."

"NOOOOOOOO!!"

(Y/n) screamed. From that point then, she was stuck with Ishimaru. Never being able to get away from the killer, many guys died by the hands of Masato from that point on.
