Somehow you need to win her attention...then you must speak to her and you'll see if your love for her is real!
I will tell you about my experience. First of all,i do not think you ve got a chance man.NO offense,if she didnt talk to you she may not find you attractive.Secondly,if you decide to try-go to her tell sth like -hey whats up,i am [name] nice to meet you.If she tells you ''me too and tells her name'' this is a good sign.Try inviting her to a cafe but it would be better if you invite you next time.For example u get to know to her,the next day see her and tell ''hey [name] i was thinking if u want to come to a cafe with me or sth''If she tells u no,or some kind of excuse-forget her.If she doesnt have time right now -she will postpone it for tomorrow,but if she refuses-forget it.It is just a pussy.
