I'm Yours~Mikey Cobban

Slut!

"Hey baby!" Zoe shouted at Mikey after numerous amounts of kisses and hugs.
" I thought I would surprise you because I missed you so much!"

"I only saw you yesterday?" Mikey said. He didn't seem as happy that she was here.

"Yeah but I wanted to see you again!" She screamed. Her voice is so high pitched and squeaky, it sounds like she's always screaming.

"I'm sorry babe, but I'm spending the day with Lily." Mikey answered back.

My heart sank.
Did he really just cancel on his girlfriend for me?

Zoe's mood automatically dropped.

"Can we go talk outside?" Zoe asked. Well, she didn't ask, it was more of an instruction. She didn't seem happy.

Mikey and Zoe went outside and stood in the park opposite the road of the flat for about twenty minutes. I started to hear shouting, screaming and swearing coming from their conversation.
The noise was getting closer and closer to the flat when Zoe stormed in, grabbed her bag, slowly walked over to me, stood still opposite me for a few seconds then,
she slapped me across the face. 
"Slut!" She half shouted half whispered whilst I was covering my face in pain.
"You're welcome to him!"

What just happened?
