My Master Only: Yandere Neko X Reader

The death of Kai

(A/n: I just had too. The picture is Kai. I do not own this picture full credit to the creator >:3)
(Y/n's) P.O.V~
I my phone timer buzzed reminding me that I was going to the movies with Kai. I smiled softly as I made Sai's food for tonight. "Sai, here kitty!" I called and immediately Sai appeared beside me. "Master (Y/n)! Are you going somewhere?" He asked innocently but to you it sounded a bit creepy. "Oh I'm going to the movies with Kai tonight okay?" I said politely. "All right." He said his ears drooping. With that he took his plate and walked to the guest room which he claimed as his own.
Sai's P.O.V~
'How dare he try to steal her from me!(Y/n) is mine and mine alone. I didn't want to resort to this but he is trying to take her away. I just might have to kill to keep my precious Master (Y/n) mine forever.' I thought as (Y/n) opened the door. "Sai I'll be leaving now don't stay up waiting for me okay?" (Y/n) said cutely. "Okay Master!" I said with an innocent face. (•\\w//•) Then she left and I snuck out behind her in cat form.
I followed them silently and when they got to the movies. (Y/n) was laughing at something he said. 'She's only suppose to laugh with me.' I thought and then I saw my chance to strike Kai's phone went off and he walked into the alley way I was in. After he finished talking I got his attention. He knelt down and I transformed to my neko form and covered his mouth with with my hand dragging him deeper in the alley way. He surprisingly was really weak.
This is a gore moment if you don't like gore I suggest you please skip.
I found an old piece of pipeline and some twine in the very back of the alleyway. I tied his arms and legs together with the strong twine. "Nobody that likes my precious (y/n) will live?" I whisper yelled. His screams where muffled by a piece of my shirt I had ripped off. I then began to hit him. I crushed both of his knee caps and arm joints. Then I drove the pipe straight through his eye.
(A/n: FATALITY!!! *is slapped*)
I was covered in his blood as I grabbed his phone and texted (Y/n). 'Hey something came up in my family I had to leave immediately.' 'Oh okay that means I get to spend more time with my kitten!" (Y/n) responded and I smirked. 'If only you knew what you did to me (Y/n).' I thought purring.
(A/n: Okay Sai snapped, that gore part reminded me of a video game I played. I wonder what will happen next. Please comment if you want me to add anything, person, oc, or moment in the up coming chapters. Author-chan out!)
