Falling for the boy with a black and white heart (rewrite)

THE BETRAYAL

About a month after Sarah and I started dating, we decided that we should do something to commemorate our first month together, so we decided to get each other gifts. We agreed that it should be something small and inexpensive. I went to several gift shops trying to find the perfect thing and finally found the perfect gift, a small anime couple magnet necklace at Gameplay.
We met as we arranged at the park and exchanged gifts. I was really surprised that she got me a couple's bracelet that really matches our personalities and she was delighted by the necklace I got for her. The gifts were nearly a perfect match and we had chosen them independently. It really spoke volumes to our connection.
We walked through the park looking for a good place to enjoy our picnic, with a blanket under my arm and a basket in my hand. We talked alot about future plans as we walked. We both wanted to broaden our relationship, but neither of us was sure what to do next, as we were both new to this.
We decided to take a break on a bench just off the path. "Maybe we could ask Y/N or your brother about what we should do, I am sure they have more experience at this than we do.", I suggested and she looked at me with a serious expression on her face when she replied, "I will not talk to my brother about this, he already does not approve of us dating." At that moment we heard a strange rustling in the bushes across from us. I looked to see what it was, but did not find anything. Sarah went around to the other side and disappeared from my view.

Peter's POV:
Mumbles under my breath "Fuck they heard me." Sarah comes running around the bush, sees me through the bushes and pulls me out by the ear. "ow! ow! ow! Ow! Sarah that hurts!" I said as she threw me out of the bush. "What the heck do you think you're doing here!" I look up at her looking between her and my feet as I twiddle my fingers. "I was just taking a walk and I fell into that bush, thanks for helping me out of it.", I lied to her. "Peter, I know when you lie. I'm your sister. I grew up with you so tell the truth now or I tell Y/N your secret!" "oh fuck i'm in big trouble. I better tell her." I thought to myself and said, "Fine Sarah, I've been following you but what did you expect? I'm your older brother. Do you really think I am going to sit back and not try to protect you from yourself?"
Sarah prepares to back slap me and I run. Running blindly, not paying attention where I am going. When I suddenly run into someone, knocking them to the ground. Quickly, I collect myself, look to see who it was I collided with and find it was Y/N. Seeing me Y/N scrambles to her feet and runs away before I even have a chance to apologize.

TK'S POV:
I hear rustling and Sarah yelling on the other side of the bush, I rush around the bush to see Peter running away. "What the heck?"I asked as Sarah took my hand in a huff and dragged me behind her for a short while and turned to me. "My stupid brother has been stalking us. I am going to kill that idiot.", She said fuming. "Sweetie calm down, it's ok let's just talk this all out together kay? " I said, trying to calm her down. "Do you think I could stay at your house for a while, to cool down? I can't deal with him right now.", I smiled and said, "Yeah, I don't think my mother would mind neither would Y/N you two are like siblings."
