I need help adding an options for users to favorite the listings posted on my site

I need help with coding my site. I want there to be an option where users can favorite properties on my site. This should then go into a favorite list where they can see other students who favorite the same listings and allow them to connect with each other to find a potential roommate

For example if there is a star on the listing and when they press it, it goes into their faviorte.

Would anyone know how to do this? Right now I have been told I need to create a wix store, is there another option?

Thank you to whoever sees this
