Yandere diaries. || Toby x reader. A new (possible) series I got the idea to do of the creeps doing diaries showing them gradually becoming yandere.
3k words. CW: Yandere, adult content (mentions of arousal and references to masturbation), descriptions of violence and gore, unhealthy relationships, severe abuse, delusions, Toby slipping into insanity and also being an unhonest/unreliable narrator with how awful he’s being.

I met someone new today! We bumped into each other at a park I like to go to on Earth. They were so kind to me. We ended up getting ice cream together and exchanging numbers. I hope I can see them again soon.

I’ve been able to see them a couple more times. We’ve been messaging regularly, and have also called a couple of times. I’ve never felt so connected to someone so quickly before. We have a lot in common, and they don’t even mind any of my tics or odd quirks. We have a plan to meet up this weekend and go to the movies together, I’m really looking forward to it. I hope we continue to be friends with each other for a long time!

I just got home. We had such a fun time at the movies! We saw one of the more recent horror films together. They got scared partway through and clung onto me to feel better, and it made me feel really happy and protective over them. I wouldn’t mind seeing more horror movies with them in the future if it means that they’d do that again. We haven’t known each other very long, but I feel so connected and interested in them, I feel sparks every time they touch me. Is this what falling in love feels like?
6/21/22 -
I haven’t been able to see them for a few weeks because of our schedule differences. I feel like I’ve been excessively sad because of that. I just feel like my life is so much dimmer without them. I wanna go to the park with them again, eat ice cream, and curl up under a tree with them. I wish I could be with them every day.

We haven’t known each other for a very long time, but I’m certain they’re the person I’m meant to be with for the rest of my life. They make me the happiest I’ve ever felt, they understand me like nobody has ever understood me before, I just feel so carefree and excited in their presence. I think they might feel the same way about me too. I need to try my best to build up some courage and ask them to be my partner before someone else can.

I asked them on a date and they said yes!! I’ve never felt more excited than I am right now!! We’re going on our first date in a few days. I need to make sure I have a nice outfit to wear because I want to take them somewhere nice to eat, and then we’re gonna go for a walk together and stargaze. My life truly feels so complete and wonderful right now, I feel like I’m finally on a path to keep getting better with them in my life!

I haven’t been dating them very long, but I convinced Slender to allow me to invite them to Thanksgiving dinner. Normally we have to date our partners for a year, but I just know our relationship is going to work out, so I don’t feel the need to wait that long. They had so much fun meeting everyone, and they were happy the whole time. I felt a bit jealous that they didn’t pay as much attention to me, but that’s okay because there were so many new people they had to meet. I’m sure next time I invite them over they won’t pay anyone else any attention. I’m looking forward to having them over here more often!

I got into an argument with Jeff today. I had them over to visit me, and I stepped away for a minute to get us some snacks and Jeff so rudely decided to try and steal their attention from me. It isn’t fair! He was trying to make them laugh and hang out with him instead of me!! I got really angry and I started yelling at him, and he yelled back at me, claiming he wasn’t doing anything wrong. He’s not allowed to just walk up to them and act like they’re buddy-buddy. They’re my partner, and they’re here for me. Nobody else has the right to their attention but me.
12/25/22 -
I got to celebrate my first Christmas with them today. We spent a little bit of time downstairs with the others, but then I wanted to bring them upstairs to my room so we could be together alone. I gave them a bracelet with our names on it so that everyone would know they belonged to someone, and they seemed to like it. However, I got a bit upset at them. They said they had to go home so they could celebrate with their friends and family too, but aren’t I good enough? Aren’t I their family now? It doesn’t make any sense to me why they couldn’t just stay at the mansion, but I let them go. I’ll have a talk with them about this later.
1/24/23 -
We had another argument again. They have this friend that keeps overstepping his boundaries and I don’t appreciate it. He’s been hogging their attention recently and hanging out with them more and it’s seriously fucking pissing me off. They wouldn’t stop talking to him so I had to lie to them about him to finally get them to back off from him a bit. I wouldn’t normally want to do that, but it’s for their own good. Nobody should be hogging them away from me that much. Their friends are lucky I even allow them to talk with my dove at all. I think that’s what I’ll start calling them, now that I think about it. My sweet, soaring Dove.
2/17/23 -
I ended up getting into a fight with one of Dove’s friends. I was trying to make sure I could spend Valentine’s with Dove, but this friend wanted to be able to see them that day since he’s going on a trip soon or some other stupid excuse. It pissed me off. IM their boyfriend, that day is for US. I confronted him to get him to back off but he had the nerve to stand his ground. I had to beat the shit out of him to get him to understand his place. It’s been three days, and apparently, he hasn’t contacted them since. Good. One less pest I have to worry about. Dove was a little suspicious when I came home with torn-up knuckles that day, but I just told them it happened during training and they believed me. They even took the time and care to bandage me up. They really are so special to me. Nobody else can have them.

I’ve never really thought much about blood before. When it’s on myself or my victims, I’ve never really cared about it, I’ve actually usually thought it was gross, but it was different today. Dove got this gash when we were out on a hike from tripping and slicing their arm on a sharp rock. Normally the blood wouldn’t have bothered me, but it was just so pretty. The red spreading across their skin was just so alluring. Of course, I got them cleaned off and patched up as soon as I could, but my heart is racing just remembering it. I can’t believe I’m saying this, but I hope they get cut again soon. I have to confirm if this feeling inside me is real or just a one-off.
3/28/23 -
It wasn’t a one-off. We were cooking, and they were using one of our sharper knives. My curiosity got the better of me, and I “accidentally” bumped into them from behind. They ended up cutting themself, and their blood was just as alluring today, flowing freely out of their finger. I ended up putting their finger in my mouth to suck the blood off, and I’ve never tasted something so intoxicating before. They were a bit confused, but I just played it off and they let it go. Holy shit. I feel like I have to taste it again. I have to. The red on their skin, the metallic lingering taste in my mouth. It’s so addicting. It honestly made me a bit excited, I had to take a moment to myself so they wouldn’t notice.
4/16/23 -
I bit them. We were making out, and I just felt myself getting so worked up. I pinned them down on my mattress, and I started kissing down Dove’s neck. I couldn’t help it, my heart was beating so fast and I felt myself getting dizzy, and I bit them really hard. Their skin was so soft in my mouth, and blood started oozing out, running against my teeth and my tongue, and my lips, it was so warm and exciting, it felt like I was getting drunk. Dove didn’t like it though. They screamed and cried and begged me to stop, and I didn’t want to, but I did. I bandaged them up and apologized and feigned innocence. They said they wanted to go home early, so I took them to not get on their bad side anymore. I was so worked up though. I had to take care of myself when I got home, I was just so turned on. I have to do it again somehow. They won’t like it, but I have to. Nothing has ever felt so pleasing before.
4/29/23 -
I tried to bite them again, and they realized it wasn’t an accident this time. They yelled at me and hit me to get me off of them, and I hit them back much harder. They looked so broken and upset while they cried, but their tears and screams got me just as turned on as their blood did. The bruise that formed on their cheek was so beautiful. I held them close and apologized a whole bunch because I don’t want them to hate me. I cried a lot and I meant it. I promised I wouldn’t do it again, which I guess I didn’t mean. However, they can’t just disobey me like that. I need to try and be on my best behavior so they can be more relaxed around me. I can’t have them fighting back every time I want to do something to them.
5/09/23 -
I think my Dove needs to be caged. They’ve gotten so used to flying free that they need to be grounded and brought back to reality. I keep trying to limit their interactions with others because they keep poisoning my Dove against me, and Dove tried to fight me today. We got in a big yelling match, but I was able to calm myself down in the nick of time so that I didn’t make things worse. I got them to calm down, and we’re gonna have some space between us for a few weeks. I think I’m going to take this opportunity to my advantage.
5/30/23 -
While we haven’t been spending time together, I’ve been working hard. I found an old house in the Underworld for cheap, and I’ve been rebuilding it and fixing it up. I altered it to be able to hold Dove in without their escape, and I’m so excited about it. I’ve got a bedroom I’m setting up for them, and a nice kitchen because they’ve always liked cooking with me. I know Dove is going to love it so much when I bring them here in a few weeks. It’s going to be the best thing for us. Dove is too innocent about the world around them, and I have to be able to protect them. Nobody else can do a better job than I can.

Dove hasn’t been making things any easier. Since they last tried to move away things have been such a fucking pain in the ass. They were so scared when I locked them in here. I wanted it to be a warm welcome, where I’d bring them here voluntarily, but they had to go and ruin it because of [Redacted] sticking his nose where it doesn’t belong. They tried to run away a few days ago, and I went to write about it but I was so fucking pissed I ripped the page to shreds. I had to break their ankles so that they wouldn’t be able to run again, least not for a long while. I’ve also been keeping them tied up more, but it’s easier now that they can’t walk. The bruises on their legs are just so beautiful. I think I might keep them like this, even though they cry every day from the pain and the circumstances, but their tears are beautiful as well. I have to get more painkillers soon for them.
10/18/23 -
It’s been a while since I’ve updated. Things have been going smoother lately. Every time Dove’s ankles start to heal, I’ve been breaking them again. I just can’t trust them because they tried to escape again. I’ve been enjoying myself a lot more. I can bite them and cut them and hit them whenever I want to. I can taste their blood and chew their skin and bruise their beautiful body however I like. Of course, sometimes it makes me sad when Dove gets so upset about it. I don’t know what to do. It gets me so turned on and riled up like nothing ever has before, but I also want them to love me. They haven’t been fighting back anymore, so I think they’re getting used to it. We’ll see.
12/25/23 -
It’s our second Christmas together. I got Dove a bunch of things they asked for since they’ve been so good. They seem to have given up hope of resisting me, and it’s made me so happy. They even made me a cake for Christmas, and it was so delicious. I’m so happy we can be together again like this, just a happy couple with no interruptions. It’s truly the best gift I could have received this year.
2/16/24 -
I’ve been letting Dove’s ankles and legs fully heal. They truly haven’t been trying anything, and they’ve been so devoted to being a good partner for me, I don’t think I need to break them anymore to teach them a lesson. They can nearly stand on their own now, and they seem so happy. They said it’s because they can hug me while standing, and that made me so happy to hear. We’ve started cooking together again. We’re becoming a happy family, and I’m so glad I was right that Dove is the one for me. They even let me bite them as much as I wanted today, and they let me scratch them too, they didn’t even cry out today. I could tell they were trying really hard, so it made me very happy.
4/25/24 -
Things have still been going well. Their legs have healed up perfectly. It’s been five months since I last broke them, and I think they’re so grateful for it. They don’t disobey me, they do everything I ask, they’re so affectionate and loving with me. It makes me so happy to know that they’re truly settling into life with me. I don’t think they mind how much I hurt them anymore. They don’t complain as much, but they still cry those same beautiful tears for me. I think they’re starting to enjoy it.
5/26/24 -
I have to go on an extended trip for a week soon because of work and I’m nervous. They said they’ll wait happily for me, but I’m still so, so nervous. However, earlier this month I was gone for a few days and they didn’t go anywhere. Dove actually welcomed me back happily. I think we’ll be okay. I think this is it, the true test. I know they’ll pass, but still, I can’t quiet the anxiety in my heart. I’ll have to spend as much time as possible with them and get out all my excitement before I have to leave. I’m going to miss the feeling of their skin beneath my fingers and teeth.
