Need Help Finding an FF

I need help finding in FF which deals with Arnav and Khushi being best friends. They both get engaged but Khushi is a care free girl that is not ready to settle down yet. Arnav pampers her and lets her buy what she wants but whenever they are in public Khushi pretends that they aren't together so that no one will know about them. Arnav tells Khushi to not use him. Please help me find this ff because I lost track of it in the way and now I want to read it.
