How do I approach my introvert crush?

I (19M) have a huge crush on a girl in my batch of 100+ students. She is introvert. I have no idea how to approach her since there has never been any common interests/place/event happened where I can even get a chance to interact with her. She is just a sincere girl who sits on first bench, attends classes, leaves for home as soon as they end. I do have the courage to ask her out, but without any interactions, It will definately look creep and very desperate to her. Taking sudden steps can have high chances of denial or her saying NO. Also the after effects of denial can have consequences since we will be studying in same batch for remaining 2 years of btech as her perspective to me will change. One of my friends tells me- "don't eat where you shit". Pls help me guy, How can i make it happen😭
