Y/n's POV
              I've been living with him for a week now! And now I've grown a slight.... small.... medium... big.... huge.... gigantic! Crush on him.

              I love it when he calls me Kitty Cat! I love seeing him smile! I love hearing him chuckle! I love him in total!

              And since he calls me a cat all the time, I decided to tease him! I got a cat outfit thanks to my weak self only able to get the magic closet... and I put on the cute little outfit I have!

(Example you can change the color)

              I walked to the couch where he was sitting down. I sat down next to him and rested my head on his shoulder. He seemed lost in his thoughts and didn't notice me till later.

G's POV
              I was just sitting on the couch when Gaster started talking to me.
Hello, Son
Hi Gaster
How's it going with your girlfriend! ;)
Wtf Gaster she's not my girlfriend!
You want her to be! ;)
Stop!
Stop what? Telling the truth?
Yes- no- maybe!
Hehehehe I know everything you think about her! You even want to f-
Okay Gaster! Enough!
Fine! But you still do! ;)
Dad no!
Dad yes!
I hate you!
Love you too, son! And you should pay attention! Your girlfriend is back!

              I looked to my side to see Y/n resting her head on my shoulder. She was wearing a very flashy outfit. Not that I don't myself. "Y/n what are you-" she removed her head from my shoulder crossed her arms and interrupted me "since when did you use my name? I thought I was your kitty cat!" She complained. I chuckled "yes but still why are you-" she interrupted me again "I'm your kitty cat!" She said then made kitty cat eyes at me.

              I blushed at her cuteness. I started scratching the back of her ear again. She laid down on my lap. "Kitty you might want to get off my lap." I said as my skull heated up. "Why?" She asked tilting her head to the side. "Do you want to go to the Bonezone?" I asked "what's the bonezone?" She asked. "Just get off." I said "what if I don't want to?" She said tilting her head again. I picked her up in the air with magic. "Well now you have to! Anyways whatcha want for lunch?" I asked trying to change the topic. "I dunno!" She said.

              "Can you please change?" I asked "why?" She asked "cause you look like a slut!" I said. It hurt me to say something mean to her. I noticed her eyes get teary as she walked away to her room.

              I decided to follow her to her room and I saw her writing in a book. Once she left to the bathroom I looked at the book. I opened it to the page she just had it opened to it said "Day, I lost count 24! He hurt me... why did he say that? I thought he'd like the outfit... but I probably shouldn't be down. Something bad might've happened today! No he might just hate... Y/n you're an idiot! I just wanted to tease him cause he call me kitty cat all the time! I just wanted to joke around! But I guess I'm still not able to... know what this is stupid! He'll never like me back! I'm just acting like an idiot for no reason! Anyways I'll write later diary! See ya!
                                                 - Kitty Cat / Y/n!"

              I put her diary back where I found it and went back downstairs.
Wow you hurt her didn't you, son?
Yeah... now I feel bad.
Well she'll forgive you! I mean she does have a crush on you after all! I ship it!
Go away Gaster!
Fine.

              She came back downstairs in a normal outfit but she still looked a little upset. "Hey you ok?" I asked. "Y-yeah I'm fine!" She gave me a fake smile. "Let's go to Grillby's! Here!" I said taking off the collar. "Let's go!" She gave me a real smile this time and I smiled back at her.
