Do you think she will get fed up of me as i am shy and only she initiates convos with me every time?

I am asking because as you all know that I go for a class for preparation of exams to get into an MBA B School as I am pretty much done with college and there I have crush on this girl named Anshika in my class who is 22 or maybe 23 now and I am also 22 now. I also had crush on another girl named Khushi but looks like she is dating this guy named Harsh in our class. Anshika often tries to initiate convos with me. On our first day there(on 13th July), we even did handshake which was my first time ever I had a handshake with a girl. She asks me whether I had lunch or not and yesterday too she tried to talk. Today she didn’t come for the classes so we couldn’t meet. But I only just answer whatever she asks but I am still kinda shy to initiate any further convo with her. She is really sweet and nice to me even though i am really introvert and shy. But will she get fed up of me and stop talking as she is the one who has to initiate conversations with me every time and I never do the same with her? Will she find me boring? I am having crush on her and wanna know her more and get closer to her but i am just shy. I am afraid to message her on Whatsapp by finding her from our class whatsapp group because idk how she would react.
