Pros & Cons - Yandere! RK900 x Male Reader

RK900, or Nines as Y/N called him. He was "better" than his predecessor. Much more reserved and much more resistant to deviating from his code. Well, that's what was intended. He started to malfunction when you gave him that cute little nickname. He loves and resents you for that, you made him this way. He doesn't talk much, so he makes a wonderful listener. "It's just so beautiful. Experiencing feelings for the first time, being truly alive, it must be scary but a wonderful feeling to experience that." Y/N said, crying a little. Nines wondered if that you favor deviants so much why, are you even here? Why did you accept the transfer from working homicide in your home state to work with capturing murdering deviants in Michigan? You truly confused him, but that captured his interest.
Y/N was at his desk looking through files. Nines at his desk that's across yours doing some paper work. And admiring you. Your phone rang, ruining this perfect moment. "Sorry Nines, I gotta take this." He ran off outside. Nines followed, without you noticing. He was worried about you, no other reason.
Y/N got a phone call from the Captain at his old station. She's saying that you can transfer back if you wish since, androids deviant or not, are free. "I'll think about it." Y/N said. You just stood there, in the cold, thinking about what to do. Nines hacked your phone, listening to the call. What will he do if you move away? Why would you want to leave him? You can never leave.
Nines went back inside, you went in later. Nines went to talk to his "brother", Connor. You had an idea, make a pros & cons list, it's what you did when you were a kid.

Staying
Pros, I have friends here, I already have an apartment, I have a nice partner, my coworkers are nice, I found a really nice food truck with the best tacos ever.
Cons, I don't have any family here, the snow can be annoying sometimes.

Moving Back
Pros, I have family and friends there maybe they'll let me crash while I find a new apartment, I could eat at my favorite Chinese place again
Cons, I'd have to get a new apartment, I'd have to leave my new friends and Nines behind.

Y/N sighed and got up from his desk to take a break and get some water from the break room. Nines returned to work. He looked at your desk, his led turning red than back to blue as he tries to regain composure . Were you seriously going to leave him?!
Work was finally over, the weekend is here. Y/N was happy, he can laze around all that he wants. "Nines?" He looks around for his partner so they can go home. Y/N walks around the office asking if anyone has seen him, they haven't. He was puzzled, where could he be. He decided to check the rooms in the building. The break room, the holding cells, interrogation room. Then, the evidence locker. Y/N found Nines leaving. Nines was surprised, his led turning yellow then back to it's normal blue. "Whatcha doing? It's time to go home, I'm tired." He asked. "Oh, I was just checking something to due with a case." Nines said calmly, hiding something in his pocket without Y/N noticing. "Let's go!" Y/N smiled which made Nines cheeks turn blue.

"Is it okay if I make dinner?" Nines asked. "Sure! You don't have too though, I can do it myself." Y/N answered. "It's okay. I'll start dinner" Nines replied.
Y/N went to his room. He changed his clothes and washed his hands. While, Y/N was getting ready, Nines got to cooking. He pulled something out of his pocket, a sedative he got from the evidence room and added it to the delicious meal he was preparing. Y/N sat down on the couch and watched some television, "That smells really good, Nines!" He complimented while watching his favorite show. "Thank you. It's ready now, I hope you like it." Nines prepared a plate for Y/N. Y/N sat at the dinner table, "Do you wanna eat with me? It feels weird being the only one eating."He took a seat and began eating. "I'm okay. Do you like it?" He sat down across Y/N. "It's really good!" He  complimented. Y/N started feeling dizzy, sweat dripping down his forehead. His eyes started to close and he slumped down in his chair, hitting the table.

"Did I kill him? I'm sure I got the dose right.."
Y/N's eyes slowly opened, he tried to get up but handcuffs stopped him. He looked around the room and saw Nines. "What the fuck?! Nines get me out of here! What did you do!?" He started screaming and thrashing. Nines started shushing him and gently petting his hair, "Calm down, It's okay." He tried to lower Y/N's stress level. "I had to do this, because tou were going to leave. I saw your list." Nines' led started going red but went back to it's normal blue. "What? Is this what it's all about? Are you crazy?! I was planning on staying, you fucking weird robot!" Y/N yelled, thrashing once again trying to escape. "I knew it, I knew you'd never try to leave me!" Nines hugged Y/N, "We'll be together forever. You can never leave me, Y/N." He added, his grip getting stronger.
