When he came near me , my heart was beating so hard that he could hear it.He kissed me first time , and i don't know why but I kissed him back for the 2nd time! He pushed me on the ground , so he was laying on me!
''You Know...'' he was still kissing me '' You know that i love you!'' he said that and I blushed.
''I know .. , becouse i feel the same way about you.'' i replaied .
He was still kissing me but this time on my neck. I could feel his breath.

Christina's POV
I am so bored ahh..What should I do next ? I was thinking to myself but suddenly I heard someone singing right behind me.It was Zayn ... He sang:

So girl come on, you got it wrong
To prove I'm right I put it in a so-o-ong
I don't know why, you're being shy
And turn away when I look in to your eye eye eyes

....

Baby you light up my world like nobody else
The way that you flip your hair gets me overwhelmed
But when you smile at the ground, it ain't hard to tell
You don't know
Oh oh
You don't know you're beautiful!

I didn't know what to do! He is so sweet!
He came near me and kissed me!
''What is this Zayn?'' I asked.
''It is just better way to say I love you!'' he said that with cute smile.
