How did this Happen?

Chapter 34

Edwin POV
 Lizzie walks downstairs with her hair up in a ponytail and she is wearing a pair of jeans and a soccer t-shirt. She looks so cute. I look up at her and see she looks either mad or disappointed. "Whats wrong?" I ask. 
"We can't keep doing this Edwin." she says bluntly. 
"Do what?" I ask. I act as though I'm stupid but I know what she is talking about. We have been sorta dating for the past two weeks but it hasn't really been working so I hope she's calling it off. 
"This whole thing with you and I. We can't keep dating." she says. 
"Im so glad you see it too. We aren't meant to date we are meant to be brother and sister." I say. 
"We had a good run." she says with a smile. 
"No hard feels?" I ask. 
"No hard feels." we shake hands and she looks at me straight faced now. "Something wrong?" I ask. 
"Well we just broke up." 
"Yea" 
"Dont you think someone else needs to see the same stuff we do?" she asks. I know instently who she is talking about. 
"We have to tell don't we?" I say sort of like a question. 
"Im afraid so." she says. "I think they had sex last night." I look at her in dismay. 
"What?" I ask. 
"You heard me. They had to of. I know they did I heard them." she swallows some spit before countiuning. "Casey screamed Dereks name." Lizzie looked grossed out. I was use to hearing Derek with girlfriends. I understand how Lizzie feels, the first time I heard a girl yell Derek's name I thought they were fighting so I went to check it out to clam the mood. They weren't fighting but Derek fought me later on that night. I sutter from a chill that come over me with this thought. "I know think of how I feel. Casey was moaning and Derek was groaning and it was a horrible thing to listen too. I'm surprised Marti didn't ask about it." she explains. We hear footsteps from upstairs and we drift apart. Or at least I moved a bit realizing that we are a few inches from one another. 

Casey POV
 I wake up the next morning and hear voices coming from downstairs. I get up and ru to the top of the stairs and see Liz and Edwin talking up a storm. Lizzie has a look of disgust on her face and dismay on Edwin's. Wonder what they are talking about? Before I could walk downstairs to find out someone comes up behind me and wraps their arms around my waist turning me around. "Morning." Derek says kissing me gently on the lips. When we part I smile. 
"Hey! What do you want to do today?" I ask wondering if he wants to go out and completely forgetting about Edwin and Lizzie. 
"I don't know just hang out here?" he says. I smile. 
"Sure you worked us to the bone yesterday anyway." he backs away from me a bit. "What the matter?" I ask. 
"Um. Oh nothing but did you forget that we were broken up." Derek asks. I shake my head. "Then why did you- 
"Because I wanted to Derek." I say cutting him off. 
"But why?" god he asked a lot of questions. 
"Because. Because I... I love you." I say. 
"What?" 
"I love you Derek. I don't know why but I do. I always have deep down. I know we fight and you slapped me but that's not a big deal to me. I love you and your cocky smile and your hair and the way you look at me I love everything about you." I feel a tear roll down my face. He looks down. He can't stand tears. We are silent for a long time. "Derek will you say something?" I ask him. 
"I love you too." He says. We had grow far apart so I run up and grab his head and kiss him passionately. We go back into his room and he lays me on the bed like before.
 The rest is HISTORY.
