Help me find this ff please.

Hi, I have read this ff long time back. Kushi's twin sister and arnav are married years back and on that day both parents of arnav and kushi die and Arnav have broken the marriage that day itself. Kushi comes to work in arnav's house and later it is revealed that kushi's sister eloped on the marriage day and kushi replaced her. Shyam is antagonist. Can someone please tell the name of this ff?

I think its "Unknown". You can check on google by typing arshi ff unknown you will easily find the link there. Similarly type of story is currently going on with name as an Unknown wife by Miss wow in facebook.

Yes!!! That's I was looking for. Thank you so much...🤗🤗🤗
