Need help with Arshi fic

Hi I am looking for a Arshi fic where Arva and Khushi are from same school. I think Khushi is his junior. Aman is Khushi’s cousin. He is a friend of Arnav. Aman keeps pushing Arnav and Khushi together without them knowing. After schooling they get into a relationship. Kushi is studying medicine and Arnav leaves to Harvard. Before Arnav leaves to the US there is a small misunderstanding between them. For 2 yrs they are not in touch very much and Khushi is engaged to Shyam by the time Arnav returns back to India. Arnav’s nani doesn’t accept for their marriage proposal because of some kundali issue. After Arnav comes to know this, they get married in their friends presence.

I know it’s very known fic, but I can’t remember the name. Can someone please help me. Thanks
