Finding arshi ff

I am searching a ff on arshi in which arnav and khushi got married.. Initially arnav thinks him to be gold digger.. There this incident where anjali and khushi act as tv serial characters and arnav misunderstood khushi.. In a in another incident Arnav things that she had pushed Anjali on stairs but inreality she had saved Anjali. In another incident Arnav goes to Khushi is college as chief guest to surprise herbut after knowing that she is dancing with another person he threatens that person and instead dance with her on Teri Mer. On anniversary he gives Khushi an option to stay or to leave hi. In between they both go to Shimla andN Nainital also..Also he arranges for security for khushi please if anybody remembers tell the name of this ff.
