How can I bond with two cockatiels in the same cage?

I just got two cockatiels both under 1 year old. One girl and one boy. So far, they've spent their entire life at the pet shop in a cage together. Now at my home, I also have one large cage for them. I'm starting to regret my decision of buying two birds and 1 cage because I hear that tiels which bond with eachother won't bond with their owner as well. Is there a way to prevent that? I want them both to be close to me but I don't know how big of a problem them being close to eachother is.
