Angel vs. Devil

I cared about you.
As if you are someone important in my life,
well, in fact you are;
but I can't let you know.
Maybe if I tell you,
we can't be friends again.
You are so addictive.
and slowly drug me and I could not forget you.
I know you are attractive,
Not only to me, but to others as well.
You are too competitive,
Which makes me lose my confident to come to you.
You seems to know my feelings
and yet, you play with it.
What can an angel do,
when she fell in love with a devil?
