I wouldn't target one specific person if I were you, just due to morals. But there is an attraction spell I found a while back that can make you seem more approachable.
You will need:
1) A mirror,most any kind, other than compact
2) 2 candles, of any color---pink is a good choice, as it brings friendship and romance
3) yourself :)
in a place that is comfortable for sitting a while, and fire safe, place the mirror with a candle on each side. Light the candles...turn down, or off, any artificial light. Now, sit down in front of the mirror, gaze at your reflection. Sit comfortably, and relaxed. Notice all your good qualities...focus on them...then say aloud how wonderful this feature (eyes, for ex.) are..notice their shape, and color, speak of them aloud...do this with all your best features..smile at yourself :) Tell yourself, how wonderful you are...state all the positive aspects of your personality, (your humor, your willingness to help others, etc) name all the beautiful traits, that make you special...speak of them aloud, and with confidence...(It may not be as easy as it sounds!) Now comes the really hard part....hopefully, with practice, and by doing the above things, this will be easier to do! ~~~Say these words~~ (or whatever suits YOU!) :)
I am beautiful (or handsome) on the outside
I am wonderful within
I am special unto myself,
So let the love come in!
Negative thoughts, they vanish
I now toss them out
Negative feelings, be banished,
To let my love shine out!
Repeat this, at least 5 times per sitting. And do at least, once a day--you may reuse the candles
