Going back to old job

So I had an amazing job that I had to quit a few years ago due to the circumstances at the time. I left on good terms. Where I've been working right now is not ideal and my hours have been cut due to covid. My old place is hiring again, and I'm thinking of applying. My circumstances are different now and I could pull it off. However I'm a little worried what will they think since I quit and now I'm trying to come back? Anyone done this, please share your experience.

Thanks
