Finding a Story

I am searching for a OS . It's about a holi party where ETF is invited and the ETF Girls Aisha,Sakshi and Liza learn that Sameer, Arjun , Shree and chotu are already married .i can't remember the OS name . Hope someone can help me.

I'm also searching for a FF where Arjun is married to Riya. And she gets shocked to know that Arjun had been married before after she breaks a picture of Roshni. I only remember a bit of back story of Riya his mother was second wife and never got accepted by her father I think due to which she has a trauma about it. I think Arjun agreed to only marry riya and asked his father to tell about his first marriage but his father hides about it .
