Project kill the killer BL

As a natural at killing since I was 5 I climbed my way up the ladder of success as an assassin. My first kill was a creepy old neighbor that tried to take me and my sister. He had his mind set on selling us when we were young and just the right type of product for the black market. He wanted his dirty hands on some quick cash. It was me and my younger sister outside playing bus driver. The sun was going down so mom had called us to come in. My sister wanted to go inside. However, I wanted to play longer. Begging my younger sister to stay outside a little longer I called her chicken. She got mad and started to cry. This eventually caught our neighbor’s attention.
Crack! I get startled by the sound of a branch breaking but play it off as a bird walking around. My sister's face turns pale white and she screams. As he comes up behind me and licks my ear I scratch him and push with my hands but can’t get him off. My mom heard the screaming and ran as fast as possible but by the time she got there he already had us. Passed out and rope everywhere keeping us in place. The bumps of the road wake me up and I look around. Shock hit me fast and I got sick. I inch away from my vomit and look around. I don’t see her. The feeling of glass ripping my insides cutting open my chest as my heart breaks makes me fall to the floor. I scream in pain knowing my sister is not here. Where is she? Why! I bang my head on the ground. I just want to sleep. I want her back. I don't want to live, take me! Why not me! I scream. But when I do , the vehicle slams on breaks and swerves to the side. Oh god what do i do?
The back door slams open the gross old man hunched over and grabs my hair. He tries to plant a kiss on me after screaming at me for yelling but I bite his face and rip a chunk of his face off. He holds his face and I go in for another bite this time his neck. I pull out his throat. He lets out a gurgling sound. At this point he is blindly swinging his arms screaming muffled by the blood gurgling in his throat and mouth. He stumbles back and no shock could’ve held me back. I wanted blood, I wanted him to hurt. I rip more and more of him apart after tackling him. He is soon left twitching on the ground and bone and flesh everywhere. He looked as if a wild animal got ahold of him. I stumbled on my feet and looked at my hands. I feel nothing? No remorse. No sadness. The only thing I feel is empty and a pit that can’t be filled. I didn’t notice that I had started crying until the tears fell to the ground and mixed with the pool of blood. Yet all my mind could think about it. My sister, my mom, my bed, my dinner cold and mom crying hurting. I fall to my knees and scream. Please! Anyone! Please.
I pass out in the blood and tears. The cold ground made me feel as if I was dead. Hours later I woke up my blinding lights. a vehicle pulled to the side. I hear talking but my weak little body can’t move. I hear a woman and a man agree on something. The two big hands from the man picked me up.
When I wake up again I'm in a doctor's office. And scans and tubes are all around me and on me. I look around but then get startled by a soft knock at the door. I cry. I just want my mom and sister.
A lady walks in and runs to me. “Oh oh oh aww honey… little one please don’t cry here hug me it will be ok.” She holds me and rocks me gently it feels comforting and my body relaxes like she is healing me with just a touch. “There there. I’ll explain everything but first let’s get your pajamas and a nice bath and food with a room and tv.” I nod and just follow as if I'm in a trance. What is wrong with me I should be fighting back crying asking about my mom and sister. Not here for a vacation! Body please do something. But my legs just keep moving!
