'am coming Wyatt' I yelled, why was he ringing the bell or did he finally learn some manners now that he has got a girlfriend. Wyatt and I were going to the park and trust me, he is early...way early.
I opened the door and the back turned against me wasn't that of Wyatt, it was a stranger.
'hello, how may I help you?' I asked, he turned around with a hood covering his face, great a stranger with a masked face. I was gonna go back inside when I felt his hand around my neck and I somehow loosed consciousness right there...

So let me warn you am not a grammarian, I can't differentiate between as and has. I'll try to correct any errors I come across so help me God.
And like I said it's not a love story but that doesn't mean there is not gonna be affection displayed.
