Please help me to find a story in which Arjun has a daughter niti (I think so) she and Riya are of same age and both are friends of college . Arjun is married and elder from Riya and they both fall in love
This is a joint story I don’t know of which writer. So if anybody knows kindly help me to find it.
Thank you 🙏
