Confusing Love (Yandere Frisk, Chara, and Betty x Reader)

Fighting Betty (Chapter 3)

"Betty." I said, turning to face. But his/her response completely threw me off guard. She hugged and tackled me. "What.... the.....heck?" I gasped between breaths. "Hello (Y/N), I found you~" He/she said in a seductive way. "Please get off of me." I said. "Sure." Betty replied. "Ok, first how did you find me?" I asked. "When there's a fight happening, it's kinda hard to ignore." he/she said. "Ok, fair point." I replied "Also, stay away from Chara and Frisk. There the bad guys." he/she said. "I kinda find the hard to believe since well Frisk freed all monsters but I don't know about Chara." "Betty!" I heard someone yell. It was Frisk and Chara. Sans teleported them here. "Until next time, (Y/N), also I killed (f/n) and his/her family so they wouldn't stand between our love." she said before she pecked me on the cheek. I was devasted. "Uh, buddy you okay there?" Sans asked with a worried look. I couldn't respond. It was like my world turned upside down. (Start Music at 0:34)

I wanted to kill Betty but a small part wanted to love her. I didn't even know why but all I could think about was murdering her. "I..... must......kill......Betty." I responded using my Super Speed but Sans caught with his bones. "What are you thinking! You can't kill her, she's using you! Look at your eyes!" Sans yelled at me. When I looked at the lake I saw the reflection of my eyes. They were bright neon pink. I overcame this urge with my magic. "Urgh! Thanks. I lost control for a second!" I said. I still didn't like her but I didn't want to kill her after that. (Stop Music) "I'm going to head home." I said. "Speaking of.... do you mind if we stay, we kinda got nowhere to go right now." Chara said. (Just imagine your house is gigantic because you've made a lot of money) "Sure. You guys can use the guest rooms." I said, walking home.

As I winded down for bed I listened to my favorite song. It's called "Cold and Dark" by Outertale (Not an actual band. Just another AU.) I turned it on. (Play Music)

I finally went to bed. It's been one heck of a day, hasn't it?
